In this case, since you are dividing by 5, you only need to need to look at the last digit of each number in this product (149**2** x 177**6** x 181**2** x199**6**). Thus we get, 2 x 6 x 2 x 6 = 12 x 12 = 14**4**, where the last digit is 4.

This means that the last digit of product (1492 x 1776 x 1812 x1996) is also 4, which is the remainder.

So the answer is **E**.
