There is one variable in the original (n, n+1, n+2, n+3, n+4). Hence, the correct answer is D.
Since , 1)=2), the answer is unique and the condition is sufficient. Hence, the correct answer is D. If we apply the common mistake type 4(B), the answer is D.

ans D

in such types of problems it is always better to assume [n-2, n-1, n , n+1, n +2] as the working set.
both statement 1 and 2 boil down to n=4.
