C

From st1 we can conclude k and p can be 6&8 or -6&-8. Hence k+p=14 or -14.
Two different answers. Insufficient.

From st2 we have no clear information about k and p. They can be any value like 6&8 or 4&12. Hence insufficient.

Combining we have k and p have to be 6 and 8 only. Note that the specific value of k and specific value of p is not important. Hence sufficient.

Statement 1: K and P are consecutive even integers. But no information on whether positive or negative integers. InSufficient

Statement 2: k and p are positive gives us more than 1 set of values. Insufficient.

Statement 1 and 2 together: K and P are consecutive even integers and also positive integers. This gives us only one answer 6 and 8. Hence Sufficient.

Ans is C
