m=3m, m is odd --> 9/3=3 +ve odd integer; // eliminate --> 6/3=2 +ve Not odd integer
m=m/2, m is even --> 9*2=18 +ve even integer; // 6*2 = 12 +ve even integer, but only one condition is satisfied

hence m=9, 6 is a multiplier --> 9*6=54

IOM B :)

I can't type the square sign, so consider * as replacement.

*m = 3m , if m is odd
*m = m/2 , if m is even

*9 = 3*9 (as 9 is odd) = 27
*6 = 6/2 (as 6 is even) = 3

=> *9 x *6 = 27 x 3 = 81

*27 = 3*27 (as 27 is odd) = 81 = *9 x * 6 , so this is our answer, D

For the rest of the options, the value is not equal to 81.
Thanks
