Choose a suitable adverb clause to complete the sentence :

_________, I reminisced about my childhood.

• An entire clause modifies an adjective, a verb, or another adverb. Adverbial clauses will be divided into several groups in keeping with the actions or senses of their conjunction, such as time, condition, purpose, reason, concession, place, comparison, manner, and result. Within the given question, we've got to settle on the right adverb clause to complete the sentence. 
• Option 'A' is "While being a child", which, by using our senses, is excluded because we cannot "reminisce" about our childhood "while being a child". 
• Option 'B' is "While I drove to my parent's house," which also can not be the proper answer because "drove" can not be used with the predicate of this sentence because it's a participle. 
• Option 'C' is "While driving to my parents' house" is the correct answer because it is grammatically satisfying and might be used because of the subject to the given sentence. 
• Option 'D' is "none of the above", which we'll not choose because we've got already found an acceptable answer. So, the whole sentence would be, "While driving to my parent's house, I reminisced about my childhood." the right answer is option C.

Hence, option C si the correct answer.
