reset

Explanation:

• Option A mentions drones flying over fields and pinpointing areas where extra watering is needed. This directly relates to agriculture as it involves farming practices (fields) and a technology (drones, which are computer - controlled in this context) being used to optimize a farming - related task (watering).
• Option B is about computers helping with traffic flow in cities, which is related to urban infrastructure and transportation, not agriculture.
• Option C is about online gaming, which is a form of entertainment and has no direct connection to agriculture.
• Option D is about robotic surgery, which is in the medical field, not agriculture.

Answer:

A. Drones fly over fields and pinpoint areas where extra watering is needed.
