The problem does not provide any information on the exchange rate between camels and monkeys. Therefore, we need to use the information provided about successful animal exchanges by zookeepers to determine the exchange rate indirectly. Since we don't know the exchange rate between camels and monkeys, we cannot solve the problem algebraically. Instead, we can use the given exchanges to form a chain of ratios. For example, we are told that 8 pandas can be exchanged for 7 zebra, and that 7 zebra can be exchanged for 12 monkeys. These two ratios can be combined to form a ratio between pandas and monkeys: 8 pandas : 12 monkeys. Simplifying this ratio gives us 2 pandas : 3 monkeys. We can use this ratio to find out how many monkeys can be obtained in exchange for 10 camels: 10 camels is equivalent to 5 pairs of pandas, which would give us (5 * 3) = 15 monkeys. Therefore, the answer is D) 24 monkeys, which is the closest to 15 monkeys.
