Answer is A.

Question stem says (n-1), n and (n+1) are consecutive positive integers. Hence, one of them is a multiple of 3

Stat1: alone is sufficient

(n-1) is even implies that (n-1) is a multiple of 2 or 4

if (n-1) is multiple of 2, then (n+1) is a multiple of 4

if (n-1) is multiple of 4, then (n+1) is a multiple of 2

There is a multiple of 2 and a multiple of 4 in the set {(n-1) ; (n+1)}

as per question stem, There is a multiple of 3 in the set {(n-1) ; n ; (n+1)}

Therefore, (n-1)*n *(n+1) is multiple of 2*4*3 = 24

Stat2 is not sufficient

n=3 gives YES answer

n=6 gives NO answer
