B Correct answer
Explanation

The claim is false. A fertilized human egg (zygote) remains a single cell for approximately 24 hours before dividing into two cells. The first cell division occurs around day 1, and the embryo develops into a blastocyst by about day 5-6. Spending '1 week as a single cell' is incorrect.
