Which of the following is the correct syntax to declare a protected method named calculate in a PHP class?

Afunction protected calculate() {}

Bprivate function calculate() {}

Cpublic calculate() {}

Dprotected function calculate() {}

Step-by-Step Solution

Solution:

Step 1: Recall method declaration syntax
Access modifier comes before the function keyword, then method name and parentheses.
Step 2: Check each option
"function protected calculate() {}" has wrong keyword order. "private function calculate() {}" uses private modifier. "public calculate() {}" misses "function" keyword. "protected function calculate() {}" is correct syntax.
Final Answer:
protected function calculate() {} -> Option D
Quick Check:
Correct syntax = protected function calculate() {} [OK]

Quick Trick: Access modifier before 'function' keyword [OK]
