Answer :
D. 'Picking up the children, making afternoon snacks, and organizing outdoor activities are my jobs at the daycare center'is the correct answer.
Repetition of a chosen grammatical form or structure within a sentence is called a parallel structure. It is used to maintain balance and flow in a well-constructed sentence. Lack of parallel structure makes a sentence grammatically incorrect. In this sentence, picking, making and organizing are grammatical forms that are repeated to form the parallel structure.
The correct sentence is D. Picking up the children, making afternoon snacks, and organizing outdoor activities are my jobs at the daycare center.
A parallel structure implies using the same grammatical form or structure in a sentence. In D, "picking up + noun phrase", "making + noun phrase" and "organizing + noun phrase" are all used in the same grammatical structure. That is to say, the verb in its gerund form and a noun phrase following it.
