Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A) and (C) only
(A) Every bag must be scanned at the entrance of the mall. — Correct.
- Must be + past participle (V3) is a modal in the passive.
- The bags receive the action, so “must be scanned” is right.
(B) You had better to book the train tickets before the Diwali rush. — Incorrect.
- The given sentence says “had better to book”.
- Had better takes the base verb (the simple form of the verb, like go, eat) with no “to”.
- Correct form: You had better book the train tickets before the Diwali rush.
(C) You needn’t cook dinner tonight. We are eating at Aunt Rekha’s house. — Correct.
- Needn’t + base verb shows that something is not necessary.
(D) How dare you to read my diary without asking? — Incorrect.
- The given sentence says “dare you to read”.
- In “How dare you ...?”, dare works as a modal and takes the base verb with no “to”.
- Correct form: How dare you read my diary without asking?
