Which value is closest to the heating value of propane gas in BTU?

Explanation:
Propane gas has a relatively high energy content per unit volume, about 2,500 BTU per cubic foot when burned. This standard reference value helps compare fuels by how much heat you get from a given amount of gas. The options provided span roughly 2,400 to 2,700 BTU per cubic foot, and 2,500 BTU per cubic foot is the closest match. Keep in mind the exact value can vary slightly with conditions, but 2,500 BTU/ft³ is the common reference.
