Undefined variable in blade when passing variable from controller Laravel

So I want to return some string from model and controller, but it always says undefined variable although it passed successfully when I check it with dd($a) and dd($b). What did I do wrong ?

about.blade:

@extends('layout.template');
@section('homeContainer');

<p> {{ $a }} </p>
<br>
<p>{{ $b }}</p>
@endsection

AboutController :

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\AboutModel;

class AboutController extends Controller
{
    //
    public static function info(){
        $a = AboutModel::info();
        $b = "This data is from controller";
    

        return view('about', compact('a', 'b'));
    }
}

AboutModel :

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class AboutModel extends Model
{
    use HasFactory;
    
    public static function Info(){
        $a = "This value is from model";
        return $a;
    }
}

Routes :

<?php


use Illuminate\Support\Facades\Route;
use App\Http\Controllers\AboutController;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider and all of them will
| be assigned to the "web" middleware group. Make something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});



Route::get('/about', function () {
    return view('about', [
        "name" => AboutController::info(),
    ]);
});

the controller never run, only the callback in the web.php file runs.
this means you do not have a and b variables but only a name variable

Route declaration is not correct. Route can't handle rendered blade code as return response. Please check below code for web.php file.

<?php
 use Illuminate\Support\Facades\Route;
 use App\Http\Controllers\AboutController;
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider and all of them will
| be assigned to the "web" middleware group. Make something great!
|
*/

Route::get('/', function () {
   return view('welcome');
});
 
Route::get('/about', [AboutController::class, 'info'])->name("info");

Rest code is fine. It will work for you.

In web.php, you should write the following code:

Route::get('/about',[AboutController::class,'info']);

Thanks for the replies!, turn out I was wrong declarating the model as variable and the routes,

for the routes I change it to

Route::get('/about',[AboutController::class,'info']);

and for the controller and model I remove the static and change the model declaration

Controller :

 public function info()
    {
        $model = new AboutModel();
        $a = $model->Info();
        $b = "This data is from controller";

        return view('about', compact('a', 'b'));
    }

Model :

public function Info(){
        $a = "This value is from model";
        return $a;
    }
