Correct answer: B

Step-by-Step Solution

To find the total number of factors for any integer, use its prime factorization.

  1. Perform Prime Factorization:

    • Break down 9600 into prime factors:

    • 9600 = 96 * 100

    • 96 = 32 * 3 = 2^5 * 3

    • 100 = 10 * 10 = (2 * 5) * (2 * 5) = 2^2 * 5^2

    • Combine them: 9600 = (2^5 * 3) * (2^2 * 5^2)

    • 9600 = 2^7 * 3^1 * 5^2

  2. Apply the Factor Counting Formula:

    • If a number is expressed as n = (p^a) * (q^b) * (r^c)..., the total number of factors is (a + 1) * (b + 1) * (c + 1)...

    • Here, the exponents are 7, 1, and 2.

    • Total factors = (7 + 1) * (1 + 1) * (2 + 1)

    • Total factors = 8 * 2 * 3

    • Total factors = 48.
