We know that, log1010 = 1; log10100 = 2, and so on. Thus, log1050 will be 1.xx and by induction we can say that when log of a number is 1.xx, the number will have 1 trailing zero.
Let 253 = a. So 53 log 2 = log a.
log10a = 53 x 0.301 = 15.953 Thus, a has 16 digits.
Hence, the correct option is (c).
