(b) Amphiastral
(c) Pre-mitosis, acetric
(d) Eumitosis, acetric

Options

A. Anastral
B. Amphiastral
C. Pre-mitosis,acetric
D. Eumitosis acetric

Answer

To determine the correct answer to the question about mitosis in animal cells, we need to analyze the options provided and understand the characteristics of mitosis in animal cells.

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two genetically identical daughter cells. It is crucial for growth, development, and tissue repair in multicellular organisms.

2. **Identifying Key Structures in Animal Cells**: In animal cells, two important structures are present during mitosis: centrioles and centrosomes. These structures play a vital role in organizing the spindle fibers that separate the chromosomes during cell division.

3. **Types of Mitosis**:
- **Amphiastral Mitosis**: This type of mitosis occurs in animal cells where astral rays (spindle fibers) are present. The centrioles help in forming the spindle apparatus, which is crucial for the proper segregation of chromosomes.
- **Anastral Mitosis**: This occurs in plant cells where centrioles and astral rays are absent.
- **Pre-mitosis Acentric**: This term is not commonly used in the context of standard mitosis definitions.
- **Eumitosis Acentric**: Eumitosis refers to normal mitosis, but the term "acentric" is misleading in the context of animal cell division.

4. **Conclusion**: Since animal cells exhibit amphiastral mitosis due to the presence of centrioles and astral rays, the correct answer to the question is **(b) Amphiastral**.

### Final Answer:
(b) Amphiastral
