A
(a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
B
(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
C
(a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
D
(a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
Answer
(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
Explanation
Solution
Let associate each microorganism with its respective metabolic process.
- Nitrococcus is known for the conversion of ammonia to nitrite.
- Rhizobium is associated with the conversion of atmospheric nitrogen to ammonia.
- Thiobacillus is responsible for converting nitrite to nitrate.
- Nitrobacter is involved in the denitrification process.
(a) Nitrococcus (ii) Conversion of ammonia to nitrite
(b) Rhizobium (iv) Conversion of atmospheric nitrogen to ammonia
(c) Thiobacillus (i) Conversion of nitrite to nitrate
(d) Nitrobacter (iii) Denitrification
So, the correct option is (B): (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
