Choose the correct option which best expresses the same sentence in Indirect/Direct speech.

The teacher said, "Let the boy go home."

The teacher said that the boy can be allowed to go home.

The correct answer is Option (3) - The teacher said that the boy can be allowed to go home.

 The sentence “Let the boy go home” expresses permission.
When “let” is used to give permission, it is correctly changed into “be allowed to” in indirect speech.

Now, since the reporting verb is “said” (past tense), backshift can happen, but it is not compulsory in all cases, especially when the meaning remains general or valid.

• Option 3: “can be allowed” → correctly conveys permission and is acceptable

• Option 2: “might be allowed” → also possible, but more formal/less direct

• Option 1: “may be allowed” → no backshift (less appropriate here)

• Option 4: “would be allowed” → changes meaning to future possibility, not permission.
