102.
102 is the closest to a two digit number that is divisible by 2, 3, and 4.
What I did was I got the closest numbers to 99 and worked my way up.
100 didn't work
101 didn't work
102 seemed to be a good candidate
The correct simplification will be: (b) ab²

Here we will use the property of exponents for division of two exponential terms with same bases. The original property is : 
It means if the bases are same , then we will just subtract the exponents while dividing two terms.
Using this property:

and 
So,
