b) Need
c) Ought
d) Used

Answer 1

Hint:Modal verbs help to determine the mood of a sentence, to indicate obligation, permission, possibility, and so on.

Complete answer:

A modal verb is a type of verb that is used to indicate modality i.e. likelihood, ability, permission, request, capacity, suggestions, order, obligation, or advice. Modal verbs always accompany the base form on another verb having semantic content. Semi/quasi modals are generally modal phrases performing the same functions as modals, they form phrases with ‘to' like ought to, need to, used to, and so on.
Now, we will examine all the given options and find out the correct answer :
Option ‘a’ is Must. It refers to an obligation or compulsion. In the given sentence, we can clearly see that there is no obligation caused, so this is not the correct answer.
Option ‘b’ is Need. It refers to necessity or requirement. In the above sentence, no necessity or requirement has been shown, so this is also an incorrect option.
Option ‘c’ is Ought. It refers to a moral obligation or duty. In the given sentence, it won’t fit in. So, we'll eliminate this option as well.
Option ‘d’ is Used. It refers to a discontinued habit or past situation when placed here, it refers to a game that the speaker loved when he was a child. So, this is the most suitable option.
As we have analyzed all the given options, we can easily figure out the correct answer. Here, the correct modal verb would be “need”. Hence, option ‘b' is the correct option. All the other models are irrelevant to the given sentence.

Note: Don’t get confused between “ought” and “need” as “ought” is used for moral obligations, unlike “need”.
