Answer:
OC. No chores or obligations faced us, therefore, we actually had time to enjoy the holiday.
Step-by-step explanation:
A conjunctive adverb is a word that acts as a conjunction but also at the same time as an adverb. It connects the two sentences while also modifying the verb in the sentence.
The conjunctive adverb "therefore" is used in the given sentence. And in a correct grammatical form, whenever therefore is used in the middle of a sentence as a conjunctive adverb, it should be used alongside two commas, before and after. So, the right way to use it should be "....., therefore, ....."
Therefore, the correct answer is option C.
No chores or obligations faced us, therefore, we actually had time to enjoy the holiday.
