Verified step by step guidance

Understand the ploidy level of the cell entering meiosis. Meiosis typically begins with a diploid cell, meaning it has two sets of chromosomes.

Recall that a diploid cell contains two complete sets of chromosomes, one set inherited from each parent.

Recognize that meiosis reduces the chromosome number by half, producing haploid cells with one set of chromosomes.

Identify that the question asks about the state before meiosis starts, so the cell must be diploid with two sets of chromosomes.

Eliminate other options such as haploid (one set), triploid (three sets), and tetraploid (four sets) because they do not represent the typical starting point for meiosis in most organisms.
