Select the correct option with respect to mitosis

Options

A. Chromosomes move to the spindle equator and get alingned along equatorial plate in metaphase
B. Chromatids separate but remain in the centre of the cell in anaphase
C. Chromatids start moving towards opposite poles in telophase
D. Golgi complex and endoplasmic reticulum are still visible at the end of prophase

Answer

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two genetically identical daughter cells from a single parent cell. It consists of several phases: prophase, metaphase, anaphase, and telophase.

2. **Identifying the Phases**:
- **Prophase**: Chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.
- **Metaphase**: Chromosomes align at the spindle equator (also known as the metaphase plate).
- **Anaphase**: Sister chromatids are pulled apart toward opposite poles of the cell.
- **Telophase**: Chromatids reach the poles, and the nuclear envelope reforms around each set of chromosomes.

3. **Focusing on Metaphase**: During metaphase, chromosomes are indeed aligned along the equatorial plate. Each chromosome is connected to spindle fibers at the centromere, and the presence of kinetochores (protein structures) is crucial for this alignment.

4. **Evaluating the Options**: The question asks to select the correct option regarding mitosis. The statement provided in option 1 is: "Chromosomes move to the spindle equator and get aligned along the equatorial plate in metaphase." This accurately describes the events of metaphase.

5. **Conclusion**: Since the description in option 1 aligns with the established understanding of the metaphase stage of mitosis, it is the correct option.

### Final Answer:
**The correct option with respect to mitosis is option 1: Chromosomes move to the spindle equator and get aligned along the equatorial plate in metaphase.**
