Match List I with List II and selcct the correct answer using the code given below the lists : List I (Plant) A. Soyabean B. Azolla C. Pino D. Maize List II (Biofertilizer) 1. Anabaena 2. Rhizobium 3. Azospirillum 4. Mycorrhiza Code : A B C D

The correct matching of plants with their respective biofertilizers is as follows: Soyabean (A) is a leguminous plant that forms a symbiotic relationship with Rhizobium (2) for nitrogen fixation [c2][t4]. Azolla (B) is an aquatic fern that hosts the cyanobacterium Anabaena azollae (1) within its leaf cavities, making it a potent biofertilizer [t2][t8]. Pino (Pine) (C) establishes a symbiotic association with Mycorrhiza (4), specifically ectomycorrhizal fungi, which assist in phosphorus uptake and nutrient mobilization [t1][t9]. Maize (D) is a cereal crop that benefits from associative nitrogen fixation by Azospirillum (3), which colonizes the rhizosphere and promotes plant growth [t1][t2]. Therefore, the correct sequence is A-2, B-1, C-4, D-3, which corresponds to option 2.
