A. 1.2

Explanation:

Normally, a human body cell contains 46 chromosomes - 23 inherited from the father and the same number from the mother.

Most of the human DNA, or human genes, are located in the chromosomes.

Each metaphase chromosome consists of:

two sister chromatids containing one DNA molecule each, and since they are formed by replication, these molecules are completely identical in gene content; that is why chromatids are called sister chromatids;  two centromeres, one on each chromatid.
