Choose the option that best connects the two sentences. Seema got a call. She left the house immediately. 

Option A is the right answer because we employ the cumulative conjunction "and" to connect two sentences when one occurrence follows the other chronologically. So, in the supplied sentence, Seema first received a call and then promptly left the house.

Words that connect other words or sets of words are called conjunctions. A coordinating conjunction joins similar-valued words, phrases, and clauses. And, or, and but are the three most common coordinating conjunctions. They purchased oranges, pears, and apples.

A term that connects or combines together words, phrases, clauses, or sentences is known as a CONJUNCTION. A major class of conjunctions termed COORDINATING conjunctions and a subsidiary class known as SUBORDINATING or SUBORDINATE conjunctions are the two different types of conjunctions.
