Answer:

Step-by-step explanation:
In asexual reproduction, there is 1 parent and the offspring's genetics will be completely identical to the parent's.
Sexual reproduction is more complex. It involves two parents that each provide a sex cell. For the male it is the sperm and female it is the egg.
Each of these gametes (another term for sex cells) are haploid and contain half of the genetic information. The cells are like this so when the fertilize and unite, the two half-sets create one whole set for the offspring.
Based on this picture, we see there are 2 parents (1 "red" and 1 "blue).
Each provides 2 chromosomes so the offspring has a total of 4 chromosomes. 2 are red and 2 are blue.
Therefore, the correct answer must be D. Sexual reproduction is shown because the offspring received half of the genetic material from one parent and half from the other.
