Choose the sentence that is made up of Illative clause-
a) There's a lot of pending work, so I shall stay back and finish it.
b) Since Max has decided to take the kids out, I will enjoy being alone at home.
c) Sheldon decided to take the day off and go to the beach.
d) I will agree to partner with you, provided that I get equal shares of the company.

Hint: The word ‘illative' is an adjective, which means ‘of nature of or stating an inference'. But, in grammar, it means – relating to or denoting a case of nouns in some languages used to express motion into something.

Complete answer:
A compound sentence is made up of two independent clauses, which are complete sentences on their own. Illative compound sentences contain clauses where one is inferred or deduced from another; for example, “There’s someone in the hall for the light is on”, where “for” is Illative conjunction. From the given options, A contains Illative clauses, as “I shall stay back and finish it” is concluded or inferred from the clause “There’s a lot of pending work”. Hence A is correct. Option B is a complex sentence, which expresses reason and not inference, whereas the required sentence must be compound. Hence B is incorrect. In C, the sentence contains a copulative clause (using the conjunction “and”) that gives additional information while D is a complex sentence that is conditional in nature. Hence options C and D are also incorrect.

Note:
 All the other options are plausible distractions. You must know the rules of illusive clauses, and answer the question accordingly.
