17. A certain calculator is able to display at most 10 digits, so that any number with a total of more than 10 digits before and after the decimal point cannot be displayed accurately. If x and y are positive integers less than 1,000, can the result of dividing x by y be displayed accurately on the calculator?
(1) 105 < x < 108
(2) 3 < y < 6
I got confused with this problem.

B is right for sure
from (2) y can be 4,5
while dividing by 4 there can be three remainders 1,2,3 so the result will end with
0.25, 0.5, 0.75
the same argumentation 1,2,3,4 possible digits after decimal point 0.2,0.4,0.6,0.8
So (1) is not necessary here.

The concept for why B is the answer can be explained if you follow another post about terminating digits
