A: Tap root system is that which arises from the radicle of seed.
R: Adventitious roots can also arise from the radicle.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

To solve the assertion and reason question, we need to evaluate both statements provided:

### Step 1: Analyze the Assertion (A)
The assertion states: "Tap root system is that which arises from the radicle of seed."
- The tap root system indeed originates from the radicle of the seed. The radicle is the part of the embryo that develops into the primary root. This primary root can grow deeper into the soil and may develop secondary and tertiary roots. Therefore, the assertion is **True**.

### Step 2: Analyze the Reason (R)
The reason states: "Adventitious roots can also arise from the radicle."
- Adventitious roots are roots that do not arise from the radicle or primary root; instead, they develop from other parts of the plant, such as stems or leaves. Examples include prop roots in banyan trees and stilt roots in sugarcane. Therefore, the reason is **False**.

### Step 3: Conclusion
Since the assertion is true and the reason is false, we can conclude that the correct answer is that the assertion is true, but the reason is false.

### Final Answer
The assertion (A) is true, and the reason (R) is false.
