Answer 1

Hello man,
In any module quiz, there the is a comment section at the bottom left. People usually give explanations of the answer there. Check it out to find why it is 2 and not 3.

Answer 2

Consider thinking about the difference between pre-increment (++$a) and post-increment ($a++).

Answer 3

The increment is not with the variable "B". Rather it is incrementing "A" after assigning 2 to variable "B".
So, "A" is 2. "B" is assigned, Then "A" is incremented, not "B".
