Correct Answer: B.
Explanation: A fraction results in a terminating decimal if the prime factorization of its denominator consists only of the numbers 2, 5, or both. When a fraction is in its simplest form, any prime factor in the denominator other than 2 or 5 will cause the decimal to repeat infinitely. Therefore, to identify a terminating decimal, simplify the fraction and check if the denominator's factors are limited to 2 and 5.
