Refer to the given paragraph.
The two main types of root are X and Y. X roots are mostly found in plants having leaves with reticulate venation, while y roots are mostly found in plants having leaves with parallel venation.
Select the incorrect statement regarding X and Y.

Options

A. Radish, turnip and carrot are modifications of X.
B. X is found in gram while Y is found in barley.
C. X spreads horizontally hence cannot provide strong anchorage whereas Y penetrates very deep into the soil hence provides strong anchorage.
D. In Y, primary root is short-lived while X has persistent primary root.

Explanation

To solve the question regarding the incorrect statement about the two main types of roots (X and Y), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Types of Roots**:
- From the paragraph, we know that root type X is associated with plants that have leaves with reticulate venation, while root type Y is associated with plants that have leaves with parallel venation.
- Based on this information, we can deduce that X refers to **taproots** and Y refers to **fibrous roots**.

2. **Analyze the Options**:
- We need to evaluate each statement provided in the options to determine which one is incorrect.

3. **Evaluate Each Statement**:
- **Option 1**: "Reddish, turnip, and carrot are modifications of X."
- This statement is correct because these are indeed modifications of taproots.
- **Option 2**: "X is found in gram while Y is found in barley."
- This statement is also correct as gram (chickpeas) has a taproot system and barley has a fibrous root system.
- **Option 3**: "X spreads horizontally whereas Y penetrates deep into the soil and hence provides strong anchorage."
- This statement is incorrect. Taproots (X) penetrate deep into the soil and provide strong anchorage, while fibrous roots (Y) spread horizontally and do not provide as strong anchorage.
- **Option 4**: "In Y, the primary root is short, while X has a persistent primary root."
- This statement is correct as taproots have a persistent primary root, while fibrous roots have a shorter primary root.

4. **Conclusion**:
- The incorrect statement is **Option 3**: "X spreads horizontally whereas Y penetrates deep into the soil and hence provides strong anchorage."

### Final Answer:
The incorrect statement regarding X and Y is: **"X spreads horizontally whereas Y penetrates deep into the soil and hence provides strong anchorage."**
