Correct the sentence. I will come to see you sometime.
Parallel construction is when multiple parts of a sentence have the same grammatical structure. Let's analyze these.
FYI: a gerund is a verb used as a noun by adding -ing.
infinitives are the "to _" forms.
a. "Being happy," "Being sad," and "Being depressed"
All of these parts have the same grammatical structure, (gerund-adjective) so it is a parallel construction.
b. "The end" doesn't fit with the other two parts. (it's a noun but not a gerund)
c. "Dancing" doesn't fit with the other two parts. (it's a gerund but not a verb)
d. "To get rich" doesn't fit with the other two parts. (it's an infinitive, not a gerund)
Correct answer: a
