2)in the middle
3)near to middle​

Answer 1

2 option is coreect

Answer 2

Answer:

2) in the middle

Explanation:

These are X-shaped chromosomes, with the centromere in the middle so that the two arms of the chromosomes are almost equal.  

A chromosome is metacentric if its two arms are roughly equal in length. In a normal human karyotype, five chromosomes are considered metacentric: chromosomes 1, 3, 16, 19, and 20. In some cases, a metacentric chromosome is formed by balanced translocation: the fusion of two acrocentric chromosomes to form one metacentric chromosome.
