$ Air layering is performed in those plants which have many, long flexible branches near the soil level.
! Layering method of vegetative propagation is performed in monocot plants.

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 regarding air layering and vegetative propagation, we will follow these steps:

### Step 1: Understand the Assertion
The assertion states that "air layering is performed in those plants which have many long flexible branches near the soil level."

- **Analysis**: Air layering is a method of vegetative propagation where a branch is induced to root while still attached to the parent plant. It does not necessarily require long flexible branches near the soil level; it can be performed on various branches of a plant.

### Step 2: Understand the Reason
The reason states that "layering method of vegetative propagation is performed in monocot plants."

- **Analysis**: The layering method, including air layering, is primarily used in dicot plants, not monocots. Monocots typically do not propagate through layering methods.

### Step 3: Determine the Correctness of Assertion and Reason
- **Assertion**: Incorrect (air layering does not require long flexible branches near the soil).
- **Reason**: Incorrect (layering is not primarily performed in monocots; it is mainly used in dicots).

### Step 4: Evaluate the Relationship Between Assertion and Reason
Since both the assertion and the reason are incorrect, the reason does not explain the assertion.

### Step 5: Choose the Correct Option
Given that both the assertion and the reason are incorrect, the correct option is:
- **Option D**: Both assertion and reason are incorrect.

### Summary of the Solution
- Assertion: Incorrect
- Reason: Incorrect
- Correct Option: D (Both assertion and reason are incorrect)
