Which of the following should be used as an explant to generate a disease free plant ?

Options

A. Anther
B. Ovary cell
C. Shoot tip
D. Young embryo

Explanation

To determine which explant should be used to generate a disease-free plant, we can follow these steps:

### Step 1: Understand the Concept of Explant
An explant is a piece of plant tissue that is taken from a plant and used for tissue culture. The goal is to regenerate a whole plant from this tissue.

### Step 2: Identify the Options
The options provided are:
1. Anthrax
2. Ovarian
3. Sotib
4. Young ebroi

### Step 3: Analyze Each Option
- **Anthrax**: This is a disease caused by bacteria and not a plant tissue.
- **Ovarian**: This term is not typically associated with plant tissues and does not refer to a specific plant part.
- **Sotib**: This term does not correspond to any known plant tissue.
- **Young ebroi**: This likely refers to young shoot tips or meristematic tissue, which are known to be free from viruses.

### Step 4: Select the Correct Explant
Among the options, the best choice for generating a disease-free plant is the **young shoot tip** (often referred to in the context of meristem culture). The apical and axillary meristems are typically free from viruses, making them ideal for tissue culture.

### Step 5: Conclusion
The correct answer is **Young ebroi** (interpreted as young shoot tips), as they can be used to obtain virus-free plants.
