Good question......Point to remember : 0! = 1! = 1

Hence, from (2) we know that b=0.

Therefore, ab/c is equal to zero.

from (1) we do not know the value of b and hence not sufficient

Ans: B

From 1) we have:

a= (3x2x1) - (2x1) = (2x1)(3-1) = (2x1)(2)
c= (2x1)-1 = 1

ab/c = 4b and we can't arrive at a value. So (1) is not sufficient.

From (2), all we know is b = 1-1 = 0. If b=0, ab/c = 0.

The answer is therefore b
