Solution:
The English language is distinguished by eight parts of speech. They can be categorised as nouns, adjectives, pronouns, verbs, adverbs, conjunction, proposition, and interjection. Modal auxiliaries or modals are verbs used with another verb to express a variety of meanings. Based on the meanings expressed, modal auxiliaries can be categorised into five types: modals that express permission, modals that indicate likelihood, modals used to give advice, modals that denote ability, and modal auxiliaries that denote obligation. “Should” denotes duty or advice. “Shall” and “will” denote a future action, intention, command, promise, warning, or determination. When denoting future actions or activities, we use “shall” for the first person and “will” for the second and third person. Thus, the second option is correct.
