Conjunctions are words that link other words, phrases, or clauses together. Coordinating conjunctions generally connect sentence elements of the same grammatical class. The chief coordinating conjunctions are: and, but, for, or, nor, also, either…or, neither…nor.Cumulative conjunctions merely add one statement to another. Examples are: and, both…and, as well as, not only…but also'.And' helps to add one clause or phrase to another similar one. The given sentence consists of two similar clauses and in order to add them 'and' must be used. Thus Option A is correct.'Or' helps to add an alternative to an already existing positive alternative. Since the given clauses are not alternatives of one another, Option B is incorrect. We use the word 'that' as a conjunction to introduce a subordinate clause to make a statement or provide more information. Since in the sentence, the clauses are similar to one another and the second clause is not dependent on the first, Option C can be ruled out. Option D can also be ruled out as 'those' refer to people and things, situations and experiences that are more distant, either in time or physically .it cannot be used in the sentence as it is grammatically as well as logically incorrect.
