Answer 2

Answer:

orrect answer because it is different from other auxiliary verbs as it is followed by a to-infinitive, it expresses ideas such as duty, necessity and moral obligation, hence the statement with ought in it means that having good manners is a duty or necessity.

The other three options are ruled out because they are verbs that must not be followed by 'to'.
