Solution

The correct option is C
92

A chromatid is one of the two identical halves of a replicated chromosome. A normal human cell has 23 pairs of chromosomes. So, a total of 46 chromosomes. At the bivalent stage, each chromosome has two chromatids. So, a total of 92 chromatids will be there in a human cell at the bivalent stage.
