A is the correct answer because Trisha says what is wrong with today's families and then gives the remedy to fix this. On the other hand, Jerod says that "we ought to leave what is good enough alone", referring to today's families. This shows that he thinks these families are adequate.
E is incorrect because both Trisha and Jerod are of the same opinion regarding today's families being traditional. They both think they are not.
I hope this helps. Please let me know if you have any other questions or would like me to elaborate further.
