In the following question, a sentence has been given in the active voice (imperative). Out of the four alternatives suggested, select the one which best expresses the same sentence in the passive voice. Let Sumita help him.

Introduction / Context:
This question asks you to transform an imperative style sentence into passive voice. The original sentence is "Let Sumita help him." It is a kind of suggestion or instruction that Sumita should assist him. In passive voice, the focus shifts to "him" as the receiver of help, while still keeping the sense of permission or suggestion through the word "Let."

Given Data / Assumptions:

• Active sentence: Let Sumita help him.
• Implicit subject giving permission: often understood as someone in authority, not mentioned directly.
• Agent: Sumita, the one who helps.
• Receiver of the action: him.
• Verb: help.

Concept / Approach:
In sentences beginning with "Let" followed by a subject and verb, the passive construction is usually formed by keeping "Let" at the beginning and placing the object of the active sentence as the grammatical subject after it. The verb then takes the passive form "be" plus past participle, and the original subject is introduced by "by." Thus, "Let Sumita help him" becomes "Let him be helped by Sumita," which keeps the same core meaning in passive voice.

Step-by-Step Solution:
Step 1: Identify the receiver of the action in the active sentence: him.Step 2: Move "him" immediately after "Let" in the passive sentence so that it becomes the central focus.Step 3: Form the passive verb phrase: be helped (be plus past participle of help).Step 4: Add the agent phrase "by Sumita" at the end to show who will perform the helping.Step 5: Combine these pieces to get: Let him be helped by Sumita.

Verification / Alternative check:
If we mentally convert the passive sentence "Let him be helped by Sumita" back into active form, we shift the focus again to the doer: "Let Sumita help him." The sense of allowing Sumita to provide help to him remains unchanged. This confirms that the passive sentence correctly reflects the original meaning and tone of the imperative instruction.

Why Other Options Are Wrong:
Option A changes the object from "him" to "them," which alters the original meaning. Option C is grammatically incorrect because it omits the auxiliary "be" before the past participle "helped." Option D incorrectly uses "He should help by Sumita," which makes the man the helper instead of the one receiving help and is ungrammatical. Option E, "He is helped by Sumita," shifts the sentence into simple present tense and loses the imperative or permissive nuance conveyed by "Let."

Common Pitfalls:
Students sometimes forget to include the auxiliary "be" when forming the passive or they change the subject and object by mistake. Another pitfall is to drop "Let" and use a simple present passive, which changes the meaning from a suggestion or permission to a statement of fact. To avoid these errors, remember that for this pattern, the passive version usually keeps "Let" and then uses "be" plus past participle for the main verb.

Final Answer:
Let him be helped by Sumita.
