Solution

The correct option is B (A)- q, (B)- p, (C)- r, (D)- t, (E)- s
Global warming is caused by greenhouse gases likeCO, CO $_{2}$ , CFC etc. An algal bloom is the growth of algae due to nutrient enrichment in lake or eutrophication. A non-renewable resource is the resources that cannot be replaced by natural mean like coal, petroleum. Rhizobium makes a symbiotic relationship with the roots of the leguminous plant and helps plant to fix atmospheric nitrogen.
Thus, the correct answer is option B.
