Answer: A) once, during interphase I
Step-by-step explanation:
Meiosis is a form of eukaryotic cell division which results in four daughter cells, each of which has half the number of chromosomes as their parent cell.
There are two major phases that a cell goes through during meiosis. About 80% of of the total cell division is interphase.
Its during interphase 1 that the cell replicates its chromosomes, where each of the chromosome has a couple of sister chromatids.
Also, the chromosomes replicate only once.
