Jamya · Answer 1

D) All the above are true

Explanation:

consider this code snippet

int age = 17;

if (age<18) {

cout<<"You are young"<
}

else{

cout<<"You are an adult"<
}

From this code snippet we see the use of an if statement which is followed by the condition age<18. We can see that this condition can only be true or false that is boolean (Fulfils option A in the question) And we know that a boolean expression is something the computer can test whether it is true or not (fulfills option B). Then finally we have used it to implement a selection control with the combination of an else branch. So all of the options are true
