Options
- A(A) - (IV), (B) - (I), (C) - (II), (D) - (III)
- B(A) - (II), (B) - (IV), (C) - (I), (D) - (III)
- C(A) - (I), (B) - (II), (C) - (IV), (D) - (III)
- D(A) - (III), (B) - (IV), (C) - (I), (D) - (II)
Correct answer
A. (A) - (IV), (B) - (I), (C) - (II), (D) - (III)
Step-by-step solution
Leaching is the process by which water-soluble inorganic nutrients percolate down into the soil horizon and get precipitated as unavailable salts. Thus, (A) matches with (IV). Catabolism involves bacterial and fungal enzymes degrading detritus into simpler inorganic substances. Thus, (B) matches with (I). Humification leads to the accumulation of a dark coloured amorphous substance called humus that is highly resistant to microbial action and undergoes decomposition at an extremely slow rate. Thus, (C) matches with
