1) B (+ + and - -)

2) A (1 2 3 4 5)

Explanation:

In the first question, the operators + + and - - are used in almost all programming languages for adding and subtracting 1 respectively from an operand.

In the second question using a while statement the numbers 1-5 is printed out because the variable n=1 is increased by 1 after each iteration.
