Assertion: 1+2 + 3 + ... n =`(n(n+1))/2`
Reason: In a statement P(n), if P(l) is true and assuming P(k) and if we prove P(k + 1) is also true then P(n) is true for all value n, n is true integer

A

Using Reason we can prove Assertion

B

Using Reason we can not prove Assertion

C

Both Assertion and Reason are incorrect

D
