To answer this question, you need to understand the concept of conditional statements in programming.
Option A) The switch & case statement - This option is correct. The switch & case statement is used to replace multiple if statements in programming. It allows you to evaluate a variable or expression against multiple values and execute different blocks of code based on the matching value.
Option B) ?:(ternary operator) - The ternary operator is a shortcut for writing simple if-else statements, but it is not used to replace multiple if statements.
Option C) The nested if statement - The nested if statement is used when you have multiple if statements inside each other, but it does not replace multiple if statements.
Option D) The #endif Statement - The #endif statement is used in preprocessor directives, specifically in conditional compilation, and it does not replace multiple if statements.
The correct answer is A) The switch & case statement. This option is correct because it is used to replace multiple if statements in programming.
