D

AI Explanation
You are correct, the answer A) an indication of nearby thunderstorm activity is the correct answer. Static on an AM radio can be an indication of nearby thunderstorm activity. Thunderstorms generate electrical disturbances in the atmosphere that can interfere with and disrupt radio signals, causing static on the receiver. This static is a useful indicator that there may be thunderstorm activity in the vicinity. The other answer choices are incorrect - static is not necessarily a sign of strong winds (B) or an indication of clearing weather (C), and it can have meteorological significance (D).
