Question

You must study hard or you will fail the exam.

a) Or
b) You
c) Will
d) Must

Answer 1

Hint: A conjunction is a part of speech that is used to connect or link words, phrases, sentences, or clauses together. So, in the above-given sentence, you have to find the word that helps in joining two sentences or phrases and make it one.

Complete answer:

As stated earlier conjunction works like a bridge between words, sentences, and phrases. Examples of such words are - but, and, yet, or, because, nor, although, since, unless, while, where, etc.
Now, let us look into the options given –
Or presents a choice between the alternatives "study hard" and "fail the exam”, it also combines the two phrases. 'Or' is an alternative conjunction that combines the clauses "You must study hard" and "you will fail the exam".
You, is a pronoun not a conjunction that refers to the speaker, it does not combine the given clauses rather it's a part of them, without which the meaning is incomplete.
Will, is an auxiliary verb that forms the tense of the sentence, it's not conjunction as it does not combine the clauses.
Must is a modal auxiliary that functions to form a mood or tense of a sentence, it does not combine the clauses, hence it isn't conjunction.
As we can see that only ‘option a’ is a conjunction and combines the two clauses. Therefore, it is the correct option.

 Note: There are two clauses/phrases here in the above-given sentence – “you must study hard” and “you will fail the exam”. You need to choose the word that connects these two and gives it some possible meaning.
