To answer this question, you need to understand the purpose of each statement and how they are used to make decisions in programming.
Option A) The switch and case statement - This option is correct because the switch and case statement is often used to replace multiple if statements when there are multiple possible values for a variable. It allows the program to execute different blocks of code based on the value of a single variable.
Option B) The ternary operator - This option is incorrect because the ternary operator is used as a shorthand way of writing if-else statements. It is used when there are only two possible outcomes based on a condition.
Option C) The nested if statement - This option is incorrect because the nested if statement is used when there is a need to check multiple conditions within one if statement. It is used to create a hierarchy of conditions.
Option D) The #endif statement - This option is incorrect because the #endif statement is used in conditional compilation to end a block of code that is only compiled if a certain condition is met. It is not used to replace multiple if statements.
Therefore, the correct answer is A) The switch and case statement.
