Answer: Option B) They are more egotistical
Step-by-step explanation:
A singly raised child is more likely to be egotistical i.e considering himself or herself to be better and more important than others.
This perception is simply due to the focused attention, endowment, care and nurture given to such a child (in the absence of any sibling) by the parents.
Thus, singly raised children are more egotistical than children with siblings
