The correct answer is

1 only

The first statement about humus being a dark colored amorphous substance is correct. Humus is indeed a dark, organic material found in soil, formed by the decomposition of plant and animal matter. The second statement, however, is incorrect in this context, as it suggests that humus itself serves as a nutrient reservoir in a colloidal form. While humus contributes to soil fertility, it does not specifically serve as a "colloidal" nutrient reservoir. Therefore, the correct answer is (a) 1 only.
