Which of the following describes the rated cooling capacity of a 30-ton system?

Explanation:
The main idea is converting tons of refrigeration to BTU per hour. In cooling, 1 ton equals 12,000 BTU per hour. So a 30-ton system has 30 × 12,000 = 360,000 BTU per hour. The other numbers would correspond to different sizes: 30,000 BTU/h is about 2.5 tons, 720,000 BTU/h is about 60 tons, and 120,000 BTU/h is about 10 tons. Therefore, 360,000 BTU per hour matches a 30-ton system.
