Which of the following is true? (A) a e Z(G) N(a) = G (B) N(a) =G a.c Z(G) (C) Both (A) and (B) (D) None of these 8 Let G be a finite group and Z (G) be the center of G. Then the class equation of G is given by: (A) o (G) =o (Z(G) +2 o(G) aeZ(G) O(N (a) (B) o (G) =o (Z(G) - o(G) aez[G) o(N(a) o(G) aeZ[a)o(N (a) (C) o (G)=o (Z(G) + A (D) None of thes C 9.
