Bclass Student {
public $name;
function greet() {

public function greet() {
return "Hello, " . name;
}
}
Dclass Student {
public $name;
public greet() {
return "Hello, " . $this->name;
}
}
Step-by-Step Solution
Solution:
Step 1: Check method syntax and property access

Quick Trick:Use $this->property and '.' to concatenate strings [OK]
