Solution

The correct option is A A-(ii) B-(iii) C-(iv) D-(i)

Column I Column II
A. Ganga action plan (ii) Ministry of environment and forests ( This is initiated to save the river Ganga from pollution) .
B. Bt cotton (iii) Insect resistant plant ( Bt toxin exist as inactive protoxins which get ingested by by insect and converted them into active form due to alkaline pH present in their gut . This solublises the crystals of Bt and create pores on the surface wall of insect gut and cause lysis) .
C. Rhizobium (iv) N2 fixing bacterium ( They fix atmospheric nitrogen into ammonia for the plant uptake) .

D. Nostoc (i) N2 fixing cyanobacteria
So, the correct option is 'A-(ii) B-(iii) C-(iv) D-(i)'
