Fill in the blank with the most appropriate option.
Abdul ___ to be a doctor.
(a)Wants
(b)Wanting
(c)Is wanting
(d)None of these

Hint: The option to be chosen should be selected while thinking about the future from Abdul's point of view. Also, the sentence refers to a future plan or an agreement which is a general truth. The answer is a simple present form of the verb.

Complete answer: The simple present tense is the way to talk about facts. It tells what is always, sometimes, or never true, or what happens over and over. It uses the base form of the verb (the infinitive without 'to') except in the third person singular. ... the verb 'to have,' (he or she has), & the verb 'to be,' (he or she is.) Now let us analyze the given options: Option(a) ‘Wants’ is correct. 'Wants' in option A is in subject-verb agreement and is the correct tense as needed. It also satisfies the hint perfectly. Therefore option A is the answer.
Option(b) ‘Wanting’ is wrong. 'Wanting' is the gerund form which has converted the verb into its continuous form which is not at all required in the sentence. Hence, Option B is incorrect.
Option(c) 'Is wanting' is incorrect as it converts the verb 'want' into an adjective which means lacking. Therefore, Option C is wrong.
Option(d) ‘None of these’ is of no use here because the correct answer which is Option A has already been chosen. Thus, Option D ‘None of these’ is void.
Therefore, option a is the right answer.
Note: While referring to the Simple Present form of the verb, the verb always ends in -s: he wants, she needs, he gives, she thinks. Negative and question forms use DOES (= the third person of the auxiliary 'DO') + the infinitive of the verb.
For example - He wants a job.
