Select true statements -
(A) Jute, flax and hemp are commercial fibres
(B) Cuticle is absent in roots
(C) The trichomes in the shoot system are usually multicellular.

Options

A. Only B and C
B. Only A and C
C. Only A and B
D. All A, B and C

Answer

To determine which statements are true, let's analyze each one step by step:

### Step 1: Analyze Statement A
**Statement A:** Jute, flax, and hemp are commercial fibres.

- **Explanation:** Jute, flax, and hemp are indeed known as commercial fibers. They are cultivated for their fibers, which are used in various industries, including textiles. These fibers are derived from the phloem of the plants, specifically classified as bast fibers.

**Conclusion:** Statement A is **true**.

### Step 2: Analyze Statement B
**Statement B:** Cuticle is absent in roots.

- **Explanation:** The cuticle is a protective layer that covers aerial parts of the plant, such as leaves and stems, to prevent water loss. However, it is typically absent in roots, as roots are usually in contact with moist soil and do not require this protective layer. Therefore, it is correct to say that the cuticle is absent in roots.

**Conclusion:** Statement B is **true**.

### Step 3: Analyze Statement C
**Statement C:** The trichomes in the shoot system are usually multicellular.

- **Explanation:** Trichomes are hair-like structures on the epidermis of plants. They can be unicellular or multicellular, but in many cases, especially in the shoot system, trichomes are multicellular. They serve various functions, including protection against herbivores and reducing water loss.

**Conclusion:** Statement C is **true**.

### Final Conclusion
All three statements (A, B, and C) are true.

### Summary of True Statements:
- A: True
- B: True
- C: True
