When studying the structure of if-else statements, we are always told that when we have two possible answers, we should choose the structure of the compound if instead of using two simple if structures. Observe the statements below and then choose the answer that supports the use of the compound if instead of the simple if. I - Greater clarity in the code, but it does not affect its efficiency. II - Greater efficiency because it reduces the number of tests in the code. III - Greater efficiency only because the code becomes more readable, since the final result is the same. IV - Only a choice of the developer, since the final result is the same. Only I is correct. II and III are correct. Only II is correct. II and IV are correct. Only IV is correct.
