'तो बाजारात गेला. तांदूळ घेऊन आला.' वरील वाक्यांचे केवळ वाक्य करावयाचे असल्यास पुढीलपैकी कोणते वाक्य योग्य ठरेल ?

The correct answer is Option A (To bajarat jaun tandul gheun aala.).

Key Points:
• A Keval Vakya (Simple Sentence) contains only one subject (उद्देश्य) and one finite predicate (एकच मुख्य विधेय/क्रियापद).
• When synthesizing two independent sentences into a simple sentence, one finite verb is converted into a non-finite participle (धातुसाधित रूप) such as 'जाऊन'.
• Option (1): 'तो बाजारात जाऊन तांदूळ घेऊन आला.' contains only one finite verb ('आला') with 'जाऊन' acting as an uninflected participle. This is a perfect Keval Vakya.
• Option (2): Compound sentence (संयुक्त वाक्य) connected by 'आणि'.
• Options (3) and (4): Complex sentences (मिश्र वाक्य) using 'तेव्हा' and 'म्हणून'.
• Therefore, option (1) is the correct simple sentence.
• Key Takeaway: A simple sentence (केवल वाक्य) has only one main finite verb; secondary verbs are converted into participles like 'जाऊन'.
