To determine the correct preposition to fill in the blank, we need to consider the context of the sentence. The sentence states that "Ram was engrossed ______ his studies." This indicates that we need a preposition that shows Ram's involvement or focus on his studies.
The correct preposition to fill in the blank is "in."
Explanation:
- The preposition "in" is used to indicate involvement or immersion in a specific activity or subject.
- In this case, Ram is completely focused or absorbed in his studies.
- Therefore, the correct sentence is "Ram was engrossed in his studies."
Alternative options and their explanations:
- The preposition "on" is used to indicate focus or concentration on a particular topic or subject. However, it does not convey the same level of involvement as "in." Therefore, it is not the correct choice in this context.
- The preposition "with" is used to indicate association or involvement with someone or something. However, it does not accurately convey Ram's focus on his studies. Therefore, it is not the correct choice in this context.
- The preposition "over" is used to indicate a position above or higher than something. It does not convey the idea of involvement or focus. Therefore, it is not the correct choice in this context.
In conclusion, the correct preposition to fill in the blank is "in," as it accurately conveys Ram's complete involvement or immersion in his studies.
