(a)Bead like structures absent on chromosomes
(b) Displacement of chiasmata occurs in diakinesis
`(c)`Separation of two basic sets of chromosomes
(d) No division of centromeres.

Options

A. b and d
B. b and c
C. c and d
D. a and c

Answer

To identify the two correct statements about meiosis, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Option (a): Bead-like structures absent on chromosomes.**
- This statement is incorrect. Bead-like structures refer to nucleosomes, which are present on chromosomes. They consist of DNA wrapped around histone proteins, forming the chromatin structure. Therefore, this option does not correctly describe meiosis.

2. **Option (b): Displacement of chiasmata occurs in diakinesis.**
- This statement is correct. Diakinesis is the final stage of prophase I in meiosis where the chiasmata, which are points of crossing over between homologous chromosomes, move towards the ends of the chromosomes. This process is also known as terminalization. Thus, this option accurately describes a process occurring in meiosis.

3. **Option (c): Separation of two basic sets of chromosomes.**
- This statement is also correct. Meiosis is often referred to as a reductional division because it reduces the chromosome number by half. During meiosis, homologous chromosomes are separated, resulting in daughter cells that contain one set of chromosomes (haploid). Therefore, this option correctly describes a key aspect of meiosis.

4. **Option (d): No division of centromeres.**
- This statement is incorrect. During meiosis, centromeres do divide, particularly during anaphase II when sister chromatids are pulled apart. Therefore, this option does not accurately describe meiosis.

### Conclusion:
The two correct statements about meiosis are:
- (b) Displacement of chiasmata occurs in diakinesis.
- (c) Separation of two basic sets of chromosomes.
