Elimainated A and B straightaway because we know that 2 or 5 gives us a teminating decimal.Then what??

Then:
c. 9=3*3
d. 12=3*2*2
e. 15=3*5
The sum of digits in 8103 is 12, it means that 8103 is divisible by 3 (i.e. 3 is one of the factors of 8103), which will eliminate one "3" from x, leaving us with only 2's or 5's in options d. and e. Only c is left.

Should be C. 15=3x5. 3 is divisible and 5 will always have a terminating decimal.

Yes, you are correct. Since when you divide 8103 by 9, after reducing the fraction, you are left with 2701 (2700 + 1) by 3. In this, 2100 can be perfectly divided by 3, by when you divide 1 by 3, you end up with an infinite chain of 0.33333333333333333......
