Here is a detailed explanation of why these modal verbs are correct:

1) Ought to is used to express advice or moral obligation. It is stronger than should, but not as strong as must. Can is used to express ability or possibility, but not obligation. 2) Need to is used to express necessity or obligation in the present or future. Needn't is used to express lack of necessity or obligation in the present or future. The difference between them is that need to is followed by the infinitive form of the verb, while needn't is followed by the bare infinitive (without to). 3) Should is used to express advice, recommendation, or expectation. It is weaker than must, but stronger than might. Might is used to express possibility or uncertainty, but not advice. 4) Can't is used to express impossibility or negative deduction. It means that something is not possible or true. Mustn't is used to express prohibition or strong obligation. It means that something is not allowed or necessary. 5) Could is used to express polite requests or permission. It is more formal and respectful than can. Would is used to express polite offers or invitations. It is more formal and respectful than will. 6) Needn't is used to express lack of necessity or obligation in the present or future. It means that something is not required or essential. Mustn't is used to express prohibition or strong obligation. It means that something is not allowed or necessary. 7) Can is used to express possibility or permission. It means that something is possible or allowed. Might is used to express possibility or uncertainty. It means that something is not certain or definite.
