Answer:
B. 46 92 92
Explanation:
The cell cycle consists of three states: Interphase, cell division and Resting.
The interphase is composed of the pases G1, S and G2 (in this order), through which the cell prepares itself for the cell divison, where a single mother cell generates two (by mitosis) or four daughter cells (by meiosis).
As part of the preparation, the cell duplicates during the interphase all its genetic material (specifically in the phase S), forming replicated chromosomes. That is to say, a chromosome with two chromatides (sister chromatides).
A human cell that normally has 46 chromosomes will have in the G2 phase the same number of chromosomes: 46, however, these chromosomes will be composed of two chromatids (instead of a single one as normally), and therefore the cell will have 92 chromatides.
Because a chromatide is made up of a strand of DNA, in the G2 phase the cell will have also 92 DNA molecules.
