PHP - Classes and Objects

Identify the error in this PHP class method:

class Car {
  public $model = 'Tesla';
  public function getModel() {
    return $model;
  }
}

AMissing <code>$this</code> when accessing <code>$model</code>

BMethod name should be <code>GetModel</code> with capital G

CProperty <code>$model</code> must be private

DReturn statement should be <code>return $this->getModel;</code>

Step-by-Step Solution

Solution:

Step 1: Check property access inside method
Inside class methods, properties must be accessed with $this->propertyName. Here, $model is used without $this->.
Step 2: Validate other options
Method names are case-insensitive in PHP, property visibility is not an error here, and the suggested return $this->getModel; is incorrect.
Final Answer:
Missing $this when accessing $model -> Option A
Quick Check:
Use $this->property to access properties [OK]

Quick Trick: Always use $this-> to access object properties inside methods [OK]
