Since (24)(25) evaluates to be some number with units digit 0, it doesn't matter what the other integers are.
The units digit is guaranteed to be 0

Given that Y= (23)(24)(25)(26)(27)
And
Quantity A Unit digit of Y
Quantity B (0).
To determine the unit digit of any number, we need to work only with the unit digits
so in this case you will multiply the unit digit of each number
3*4*5*6*7= it will give number with unit digit of (0)
Thus; Y's unit digit must be (0)
Answer is C
