Question

B) Ought
C) Had to
D) Must have

Answer 1

Hint: A verb is a term that conveys an event, an occurrence, or a state of being in syntax. It comes from the Latin verbum, which means "word." The infinitive is the simplest type of English, and it can be used with or without the particle to. Verbs are inflected in many languages to indicate tense, aspect, mood, and expression.

Complete answer:
A verb, such as hear, become, or happen, is a word that describes an event, condition, or occurrence and is the main part of the predicate of a sentence. In the above sentence, the subject has a headache and needs to take an aspirin, according to the sentence. As a result, the answer must imply that the subject requires aspirin.

Let us look at the given options:
Option A) Must: This is the correct answer. The word 'must' means 'necessity or need.' As a result, it means that the subject should take aspirin. So, it is the right answer and conveys the correct interpretation.
Option B) Ought: It is an incorrect answer. 'Ought' denotes a moral obligation rather than a requirement. As a result, it does not convey the intended significance. Furthermore, a 'to' must always follow 'ought.' Since there isn't in this situation, the sentence would be grammatically incorrect.
Option C) Had to: It is an incorrect response. 'Had to' denotes compulsion rather than necessity. It's even in the past tense, despite the fact that the sentence is in the plain present tense. As a result, using it will cause the sentence's tense to be inconsistent.
Option D): Must have: It is an incorrect answer. The phrase 'must have' implies a requirement, but it is written in the present perfect tense, while the sentence is written in the simple present tense. As a result, using it will cause the sentence's tense to be incorrect.

Thus the correct answer is option ‘A’.

Note: Verbs come in a variety of types, each of which is defined by the words that surround it and their relationship to the verb. Intransitives, transitive, ditransitive, and double transitive verbs are commonly divided into three categories based on the number of valency arguments they have. Copular verbs (i.e., be); the verb "do" used for do-support in questioning and negation; and tense or aspect auxiliaries, e.g., "be", "have", or "should", all have unique grammatical uses and therefore complements. Furthermore, verbs can be nonfinite (that is, not inflected for tense) and have a variety of special forms such as infinitives, participles, and gerunds.
