To write a conditional statement for executing some code if "i" is equal to 5, you can use the following syntax:
A) if (i==5)
Explanation:
Option A is the correct answer. In most programming languages, the double equals sign "" is used to represent equality. The condition `(i5)` checks if the variable "i" is equal to 5. If the condition evaluates to true, the code block following the if statement will be executed.
