Answer 1

Answer: (B)

Streptokinase is used as a clot-buster is obtained from Streptococcus. Methanobacterium produces biogas by the anaerobic breakdown of organic matter. Azospirullum form a loose symbiosis with maize and is used as a biofertilizer. Yeast is used for commercial production of ethanol.
