Question

Which of the following present in the soil is most helpful to the growth of plants?

• A. Gravel
• B. Humus
• C. Sand
• D. Silt

Answer 1

The correct option is B Humus

Humus is organic matter containing nutrients from the soil. It is nothing but dead and decaying organic matter where saprophytes convert complex organic material into simple nutrients. These nutrients are then available to the plants through humus.

So, option B is the correct answer.
