Answer:
B. 3
Step-by-step explanation:
Mitosis is the process of reproduction of somatic/body cells. This means that the number of chromosomes the original (parent) cell started out with, will remain the same for the daughter cells.
Given that if a parent cell has 3 chromosomes before mitosis, then the 2 daughter cells produced will also have 3 chromosomes after mitosis and cytokinesis.
