'तिने आधी सर्वांना घरात बोलावून जेवायला वाढले कारण जेवणवेळ टळून चालली होती.'
हे वाक्य कोणत्या प्रकारचे आहे ?

The correct answer is Option C (मिश्र वाक्य).

Key Points:
• The key concept is identifying complex sentences (मिश्र वाक्य) based on conjunctions.
• A complex sentence contains one main clause (प्रधान वाक्य) and one or more dependent clauses (गौण वाक्य) joined by subordinating conjunctions.
• The word 'कारण' (because) is a subordinating conjunction (गौणत्वसूचक अव्यय - कारणबोधक). It joins the reason clause to the main clause, making it a 'मिश्र वाक्य' (Complex Sentence).
• It is not a 'संयुक्त वाक्य' (Compound sentence), which uses coordinating conjunctions (like आणि, व, पण).
• Key Takeaway: Sentences joined by reason-denoting conjunctions like 'कारण' or 'का की' are Complex Sentences (मिश्र वाक्य).
