Explanation / Answer

As per Chegg policy, I am answering first 4 questions:

1.) math.pow(2,3) returns 8.0. So, option d is right.

2.) The following code will print

x is 10.1 and y is 10. So, option d is correct.

3.) Yes, you can define a variable twice in a block.

4.) x+= 2 means x = x+2 which leads to 3. Hence, option d is correct.
