Answer:
Convection current
Explanation:
Convection currents occur when a heated fluid expands, becoming less dense, and rises. The fluid then cools and contracts, becoming more dense, and sinks
Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air, the cold air due to its greater density moves downward, and the cycle continues, this upward and downward movement is called convection current.

Hello, so the verb is the action and the compound subject is going to be
our second subject in the sentence. To distinguish whether it is
corresponding or not we are going to make sure that it is in the right tense, person, etc.
So lets look at our options
Our
first sentence has the first subject plural but not the second subject,
and an improper use of the verb making this sentence grammatically incorrect.
Our second sentence the verb and compound correspond correctly so no mistakes here.
The third sentence we are distinguishing whether we use begun or began. Began is past tense and begun is past participle.
The last sentence is grammatically incorrect because the action/verb 'stores' does not correspond with our compound subject.
So that leaves us with the answer being B.
I hope I helped! If you have any other questions or would like further explanation please let me know! :)
