E=9kc/3k+c (right)
E=3k (1+2/m) (right)
1÷m=3k_2c/6k+2c (right)
E=2k (1-2÷m) (wrong)
E=3c (1-1÷m) (wrong).
So option B and E are wrong.
E=3k (1+2/m) (right)
1÷m=3k_2c/6k+2c (right)
E=2k (1-2÷m) (wrong)
E=3c (1-1÷m) (wrong).
So option B and E are wrong.

C option is correct as we know that;
G=E/2(1+u), whereas G=shear modulus and u=poison ratio so it can be written as;
E=2G(1+u) or in this question.
E=2C(1+m) as G=C and u=m.
G=E/2(1+u), whereas G=shear modulus and u=poison ratio so it can be written as;
E=2G(1+u) or in this question.
E=2C(1+m) as G=C and u=m.
