Which of the following is the correct syntax to declare a protected property named $age in a PHP class?

Avar $age;

Bpublic $age;

Cprotected $age;

Dprivate age;

Step-by-Step Solution

Solution:

Step 1: Identify correct visibility keyword and syntax
To declare a protected property, use the keyword 'protected' followed by the property name with a $ sign.
Step 2: Check each option for syntax correctness
protected $age; uses 'protected $age;' which is correct. public $age; is public, not protected. private age; misses the $ sign. var $age; uses 'var' which is deprecated for visibility.
Final Answer:
protected $age; -> Option C
Quick Check:
Protected property syntax = protected $property [OK]

Quick Trick: Use 'protected $name;' to declare protected properties [OK]
