Choose the correct statements from the given set of statements.

(A) Clayey soil contains sand and silt.

(B) Percolation of water is faster in loamy soil than clayey soil.

(C) Sandy soil has a greater proportion of big particles.

(D) Loamy soil contains humus.

`. Let's double check statements (A), (B), (C), (D): - Statement (A): "Clayey soil contains sand and silt." - Clayey soil mainly consists of a higher proportion of fine particles (clay particles). Therefore, statement (A) is incorrect/less accurate compared to B, C, and D. - Statement (B): "Percolation of water is faster in loamy soil than clayey soil." - True. Water percolates very slowly through clayey soil due to tiny pore spaces, whereas loamy soil has larger spaces allowing faster percolation. - Statement (C): "Sandy soil has a greater proportion of big particles." - True. Sandy soil is composed mainly of large sand particles. - Statement (D): "Loamy soil contains humus." - True. Loam is a mixture of sand, clay, and silt, and it contains humus, making it ideal for plant growth. Since statements (B), (C), and (D) are all correct: - Combination (B) and (C) consists of correct statements. - Combination (C) and (D) consists of correct statements. Both options `(B) and (C)` and `(C) and (D)` are valid correct options. Let's construct the response cleanly: ```html (B) and (C)

The correct option is (B) and (C) (or (C) and (D)).

Let us analyze each of the given statements step-by-step:

1. Statement (A): Clayey soil contains sand and silt.
This statement is incorrect. Clayey soil predominantly contains a much higher proportion of fine (small) clay particles rather than sand and silt.

2. Statement (B): Percolation of water is faster in loamy soil than clayey soil.
This statement is correct. Clayey soil particles are packed tightly together, leaving very small spaces between them, which retards water movement. Loamy soil has relatively larger pores, allowing water to percolate much faster than in clayey soil.

3. Statement (C): Sandy soil has a greater proportion of big particles.
This statement is correct. Sandy soil is characterized by having a large proportion of larger, coarser sand particles with prominent spaces between them.

4. Statement (D): Loamy soil contains humus.
This statement is correct. Loamy soil is a balanced mixture of sand, clay, silt, and rich organic matter known as humus, which makes it very fertile.

Since statements (B), (C), and (D) are all true statements, both combinations (B) and (C) and (C) and (D) are correct options.
