College Math CLEP Prep Practice Exam

While it may seem intuitive to pick option B, as its numbers are both prime and closer to 99 individually, we must remember the rule that the product should be closest to 99. Choosing B would give us 99 as its product, while option C would give us 104, making B incorrect. Option D may also seem like a feasible choice, with its two prime numbers and a closer individual number to 99, but its product is farther away at 105. Therefore, the best choice is C as its product of 104 is the closest to 99 and it has the added advantage of having both its numbers as prime.
