Answer:
The scenario that is the best example of energy transfer by convection is: "warm air near the equator rising higher in the atmosphere".
Explanation:
Convection is the way of transmitting heat through a liquid or gaseous medium, so the scenario that is the best example of energy transfer by convection is: "warm air near the equator rising higher in the atmosphere".
That is the best example, because the heat is transmitted throgh the air (gas), from the warmer air going up, while the cooler air goes down.
This is known as natural convection.
