96 = 2^5 * 3
Statement (1)
m is odd
m=483 = 4*8*3 = 96
you can change the hundreds and tens digit but the units will always be 3 for m to be odd.
Sufficient.
Statement (2)
hundreds digit is 8
m=843 = 8*4*3 = 96
m=834 = 8*3*4 = 96. Insufficient.
Thus, A.

Let the number m be xyz
x*y*z=96
Prime factorize 96
x*y*z=2^5*3
Statement 1
m is odd
if m is odd the the units digit will have to be odd..i.e 3
So statement 1 is sufficient
Statement 2
hundredths digit is 8(i.e y= 8 )
then here are two possible scenarios
x=4 and z=3 or x=3 and z=4
so there are two possible solutions for z.....Therefore statement 2 is insufficient...
So the ans is A....
x*y*z=96
Prime factorize 96
x*y*z=2^5*3
Statement 1
m is odd
