   Options Analysis

   Option	A (Corchorus)	B (Rosa)	C (Piper)	D (Curcuma)	Status
   (A)	II (Correct)	III (Correct)	IV (Wrong)	I (Wrong)	Incorrect
   (B)	II (Correct)	III (Correct)	I (Correct)	IV (Correct)	Correct
   (C)	I (Wrong)	II (Wrong)	IV (Wrong)	III (Wrong)	Incorrect
   (D)	III (Wrong)	IV (Wrong)	I (Correct)	II (Wrong)	Incorrect

   Option (B) uniquely aligns all plants with their botanical families, as confirmed in exam contexts like CUET PG Botany.

   Exam Preparation Tips

   Focus on economically important plants in Indian agriculture for exams like CUET. Jute (Malvaceae) and turmeric (Zingiberaceae) are frequent topics in botany matching questions.
