Which of the following options best expresses the sentence in active/ passive voice?
They are going to build a new airport near the old one.

Correct option is D

The correct sentence in passive voice is "A new airport is going to be built near the old one."

To change a sentence from active voice to passive voice:

1. Identify the subject, verb, and object:

   • Subject: They
   • Verb: are going to build
   • Object: a new airport

2. Move the object to the subject position in the passive voice.

3. Use the appropriate form of "be" along with the past participle (built) of the verb.

   • "Is going to be" is used because "are going to build" indicates a future action.

4. The active voice sentence:
   "They are going to build a new airport near the old one."
   The passive voice becomes:
   "A new airport is going to be built near the old one."

Grammatical Rule:

In passive voice for future intentions (using "going to"), the structure is:
Object + is/are + going to be + past participle form of the verb.

Grammatical Rule in Hindi:

• Passive voice में "going to" के साथ "be" का प्रयोग किया जाता है और मुख्य क्रिया को past participle (V3) में बदला जाता है।
• उदाहरण:
  • Active: They are going to paint the house.
  • Passive: The house is going to be painted.
