Which option correctly transforms the given sentence into the active voice?

Let the safety guidelines be distributed to all factory employees.

Correct Answer: Distribute the safety guidelines to all factory employees.

Explanation:
The given sentence, "Let the safety guidelines be distributed to all factory employees," is an imperative sentence in the passive voice.

Structure of Passive Imperative Sentences:
Passive Voice: Let + Object + be + Past Participle (V3) + [remaining prepositional phrase]

Rule to Convert to Active Voice:
To transform a passive imperative sentence starting with "Let" into the active voice, omit "Let" and "be", and begin the sentence directly with the base form (V1) of the action verb.
Active Voice: Base Verb (V1) + Object + [remaining prepositional phrase]

Step-by-Step Breakdown:
1. Verb: "distributed" (V3) changes to its base form → Distribute (V1).
2. Object: the safety guidelines.
3. Remaining part: to all factory employees.

Combining these elements gives the correct active voice sentence:
"Distribute the safety guidelines to all factory employees."
