Correct answer
A.   ( a ) - ( iii ), ( b ) - ( iv ), ( c ) - ( i ), ( d ) - ( ii )
Step-by-step solution
Carbon monoxide combines with haemoglobin to form carboxyhaemoglobin. High concentration of SO 2   leads to stiffness of flower buds. Polychlorinated biphenyls, are highly toxic industrial compounds. Pyrus and Vitis can metabolise nitrogen oxide.
