Suppose that a human female is accidentally exposed to a poison at one of four different points in development. If the effect of the poison is that it interferes with meiosis, at which point in the lifespan would we expect it to have the most disruptive effect? Select one: a. in older adulthood since body cells are most vulnerable at the end of the lifespan b. in the first year after birth, since this is when brain growth is most rapid c. in the prenatal period, since this is when ova are forming d. during early adulthood since this is when conception of a child is most likely to happen
