Answer: B. Kate
Explanation: This is because Kim and Kate are identical twins. Identical twins are formed when one fertilizes egg splits to form two individuals. Identical twins, unlike fraternal twins, have the same genetic make up. Although certain environmental factors may trigger different behaviours in identical twins, they are usually both susceptible to the same behavioural expression.
If Kim was put up for adoption and eventually grows up to become a criminal, Kate who is her identical twin is more likely to become a criminal than Eric and Jack whom she was put up for adoption with. This is the nature versus nurture debate and nature(genetics) usually finds expression irrespective of environmental factors.
