B. (iii) and (iv)
C. (ii) and (iii)
D. (iv) only

Explanation

To determine which statements about lymph are incorrect, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement (i)**: "Lymph is colourful as it has haemoglobin but no RBC."
- **Analysis**: This statement is incorrect. Lymph is actually colorless because it does not contain hemoglobin. While it does contain lymphocytes, it does not have red blood cells (RBCs) or hemoglobin, which gives blood its red color. Therefore, this statement is false.

2. **Statement (ii)**: "It contains specialised lymphocytes which are responsible for immunity of the body."
- **Analysis**: This statement is correct. Lymph does contain specialized lymphocytes, such as T-cells and B-cells, which play a crucial role in the immune response of the body. Thus, this statement is true.

3. **Statement (iii)**: "Lymph is an important carrier for nutrients and hormones."
- **Analysis**: This statement is also correct. Lymph acts as a transport medium for various substances, including nutrients and hormones, throughout the body. Therefore, this statement is true.

4. **Statement (iv)**: "Fats are absorbed through lymph in the lacteals present in the intestinal villi."
- **Analysis**: This statement is true. Lacteals are specialized lymphatic vessels located in the intestinal villi, and they are responsible for the absorption of fats (in the form of chylomicrons) from the digestive tract into the lymphatic system. Hence, this statement is correct.

### Conclusion:
- The only incorrect statement is **(i)**: "Lymph is colourful as it has haemoglobin but no RBC."
- Therefore, the answer is that **statement (i) is incorrect**.
