Explanation:

1. Point - source pollution comes from a single, identifiable source. Here, the leak from a gasoline tank at a gas station is a single source, making it point - source pollution.
2. Burning of fossil fuels releases sulfur dioxide and nitrogen oxides which react with water vapor in the atmosphere to form acids, contributing most to acid precipitation. Ethanol doesn't contribute as significantly, and radon and ozone are not major contributors to acid precipitation.

Answer:

1. A. point - source
2. C. burning of fossil fuels
