Mathematical Induction is a special way of proving it contains two steps
Step 1 - Base Step : prove it is true for initial value (initial value need not always be 1)
Step 2 - Induction Step : Assuming it is true for n=k i.e P(k) is true and prove it for n=k+1 i.e P(k+1) is true
Answer : B
A) False, we would be proving for P(k+1) and not for P(k) where K>=1
B) True, we would be proving for P(k+1) assuming P(k) is true where K>=1
C) False, initial value can't 0 because it is neither positive nor negative
D) False , Assuming P(k) is true is neccessary to prove it for P(k+1) where K>=1
