Answer:
D). 50%.
Explanation:
As per the survey, half of the families(50%) out of the population have been reported that their family members(one or more) have accommodated their situation of employment due to having a differently-abled child in their families. Such a child suffering from any kind of disability(physical or mental) requires care and assistance and could not left on their own. Thus, the family members(parents) need to make adjustments in their job in order to look after the child and his needs appropriately. Thus, option D is the correct answer.
