ज्या प्रयोगात कर्ता प्रथमा विभक्तीत कधीच नसतो, पण कर्म प्रथमा विभक्तीत असते त्या प्रयोगास ______ म्हणतात.

The correct answer is Option B (Karmani prayog).

Key Points:
• Kartari Prayog: Subject is ALWAYS in the nominative case (प्रथमा विभक्तीत असतो).
• Karmani Prayog: The subject is NEVER in the nominative case (usually instrumental तृतीया or सविकरण चतुर्थी/षष्ठी), while the object is ALWAYS in the nominative case (कर्म प्रथमा विभक्तीत असते), and the verb changes according to the gender and number of the object.
• Bhave Prayog: Neither subject nor object is in the nominative case.
• Therefore, the definition given describes Karmani Prayog (Option 2).
• Key Takeaway: When the subject is never in nominative case and the object is always in nominative case, it is Karmani Prayog.
