In standard form 72 crore is written as

Let us first understand the number of zeroes in a crore,

One lakh = 1, 00,000


Number of zeroes = 5


Ten Lakhs = 10, 00, 000


Number of zeroes = 6


One crore = 1, 00, 00, 000


Number of zeroes = 7


Ten crore = 10, 00, 00, 000


Number of zeroes = 8


Therefore 72 crore = 72, 00, 00, 000


Number of zeroes = 7


Number of terms to be shifted after decimal point = 8



72, 00, 00, 000 = 7.2 × 108


So the correct answer is C.
