Haploid plant can be obtained from:

Options

A. bud culture
B. root culture
C. anther culture
D. leaf culture

Answer

### Step-by-Step Solution:

1. **Understanding Haploid Plants**:
- A haploid plant contains only one set of chromosomes (n). These plants can be derived from gametophytic cells, which are involved in the reproductive process of plants.

2. **Identifying Sources of Haploid Plants**:
- Haploid plants can be obtained from gametes, specifically from pollen (male gametes) and ovules (female gametes). The process of obtaining haploid plants typically involves the use of specific plant tissue cultures.

3. **Evaluating the Given Options**:
- **Option 1: Bud Culture**: This method involves the growth of new shoots or flowers from buds but does not produce haploid plants.
- **Option 2: Root Culture**: This method focuses on the growth of roots and does not yield haploid plants.
- **Option 3: Anther Culture**: This method involves culturing the anthers (which contain pollen) to produce haploid plants through a process called parthenogenesis, where the pollen develops into a plant without fertilization.

4. **Conclusion**:
- The correct answer is **Option 3: Anther Culture**, as it is the only method among the options that can produce haploid plants.
