d) None of the above

Answer 1

Hint: Read the given sentence carefully. Try to make out the core meaning of it. Find out the subject, predicate, and object of the given sentence.

Complete answer:
 The given options are plausible adverbial clauses and we have to fill in the blank with the most suitable one. An adverb clause is a group of words containing a subject and a verb, and it functions as an adverb, by modifying an adjective, verb, or adverb. Adverb clauses generally begin with subordinate conjunction (since, because, while, etc.).
Now, let us examine all the given options to find out the correct answer :
Option ‘a' is correct because it is an adverb clause of purpose, ‘so that’ is a pair of conjunctions that refers to a purpose: “we don’t have to wait outside”.
Option ‘b' is incorrect because it contains a coordinate/independent clause whereas an adverb clause is subordinate/dependent.
Option ‘c’ is incorrect because it is a phrase, not a clause. So, we will eliminate this option straight away.
Option ‘d’ would be chosen if all the other three options are incorrect, or doesn’t fit in the given question. But, this is not the case in this particular question, so we will eliminate this option. Hence, option ‘a’ is the correct option.

Note:
 All the other options are plausible distractions. You must see and check all the parts of the speeches in the given sentence, and align the options with it to find out the correct answer.
