Correct option is D
The correct sentence is (D) The army decided to attack the enemy tomorrow.
• Explanation:
Prepositions like "on", "in", and "at" are not used before tomorrow because it is an adverb of time that already indicates a future point. Hence, the correct usage is simply "tomorrow" without any preposition.
• Grammar Rule:
With time adverbs like today, tomorrow, yesterday, tonight, we do not use prepositions like on, in, at.
• Hindi Explanation:
Tomorrow के पहले कोई preposition (on, in, at) नहीं लगता क्योंकि ये पहले से ही समय को दर्शाता है।
सही वाक्य: The army decided to attack the enemy tomorrow.
