_____ सह बालकः गच्छति ।' अत्र रिक्तस्थाने शुद्धरूपं भविष्यति

Question

Accepted Answer

Explanation:

1. **Correct Option: पित्रा (Option 3)**
   - The sentence "_____ सह बालकः गच्छति।" translates to "The boy goes with _____." In Sanskrit, the word "सह" (saha) means "with," and it requires the instrumental case (तृतीया विभक्ति) for the noun it is associated with. The instrumental case of "पिता" (father) is "पित्रा." Therefore, "पित्रा सह बालकः गच्छति।" correctly translates to "The boy goes with the father." This is why Option 3, "पित्रा," is the correct choice.

2. **Explanation of Incorrect Options:**

- **पिता (Option 1):**
     - "पिता" is in the nominative case (प्रथमा विभक्ति), which is used for the subject of a sentence. It does not fit the requirement of the instrumental case needed by "सह." Therefore, it is incorrect in this context.

- **पितरम् (Option 2):**
     - "पितरम्" is in the accusative case (द्वितीया विभक्ति), which is used for the direct object of a verb. Since "सह" requires the instrumental case, "पितरम्" is not suitable here.

- **पित्रे (Option 4):**
     - "पित्रे" is in the dative case (चतुर्थी विभक्ति), which is used to indicate the indirect object or the recipient of an action. This does not align with the requirement of the instrumental case needed by "सह," making it incorrect for this sentence.

In conclusion, the correct form to use with "सह" is the instrumental case, which is "पित्रा." Hence, Option 3 is the correct answer.
