Answer:
4) "all of the above" is a valid choice in this context. If a decision needs to be made based on multiple choices, you might use a combination of different control structures depending on the complexity of the decision-making process.
"if" statements are the basic building blocks for making decisions.
"if-else" statements are useful for handling two possible outcomes.
"if-else-if" statements are suitable when there are multiple mutually exclusive conditions.
So, "all of the above" could be a valid choice if you are open to using different constructs depending on the specific requirements of the decision you are making.
