Explanation / Answer

If you post more than 1 question, as per chegg guidelines I have to solve only first question. But I solved first 3 questions.

Ques 1. Answer : (c) if ($aVariable == 1);

In option (A) , there is no block which is to be executed when the consition becomes true.

In option (B), the brackets for the if block are {}, and not ().

In option (C), there is a semicolon(;) after the if block. It means that there is no statements which are to be executed if the consition becomes true.

In option (d), there are no brackets in which the condition is specified. The consition must be inside ().

Ques 2. (A)

We can execute multiple statemtnts inside {} block.

Ques 3. (c) else { echo "the else statement"; }

In option (A), there is a ; after else. So, the block after that is not under else.

In option (b) , the syntax in not correct. There is no hyphen( - ) between else and echo statement.
