Answer 1

The Correct Option is A

Let's analyze the sentence:
Step 1: Understand the meaning of the sentence:

• The sentence means that trained workers are necessary for the proper or effective functioning of the factory.

Step 2: Meaning of the options:

• Efficient: working well without wasting time or resources — fits perfectly.
