Researchers examined 100 people suffering from herniated disks in their backs. Five of them were found to have a defect in a particular gene. The researchers also examined 100 people who had no problems with the disks in their backs; none had the genetic defect. They concluded that the genetic defect increases the likelihood of herniated disks.
Which one of the following, if true, most strengthens the researchers' reasoning?
A. The researchers also examined a group of 100 people who did not have the defective gene; 80 were found to have herniated disks in their backs.
B. When the researchers examined a group of 100 people with the defective gene, they found that 2 of them had herniated disks in their backs.
C. When the researchers examined the families of the 5 subjects who had the defective gene, they found that 30 family members also had the defective gene, and each of them suffered from herniated disks.
D. Another team of researchers examined a different group of 100 people who suffered from herniated disks, and they found that none of them had the defective gene.
E. When the researchers examined the family of one of the subjects who did not suffer from herniated disks, they found 30 family members who did not have the defective gene, and 20 of them suffered from herniated disk.

IMO C is the answer.
Researchers examined 100 people suffering from herniated disks in their backs. Five of them were found to have a defect in a particular gene. The researchers also examined 100 people who had no problems with the disks in their backs; none had the genetic defect. They concluded that the genetic defect increases the likelihood of herniated disks.
Which one of the following, if true, most strengthens the researchers' reasoning?
A. The researchers also examined a group of 100 people who did not have the defective gene; 80 were found to have herniated disks in their backs.
-> This actually weakens the reasoning.
B. When the researchers examined a group of 100 people with the defective gene, they found that 2 of them had herniated disks in their backs.
-> This even though strengthens the argument, we keep it on hold for the time being.
C. When the researchers examined the families of the 5 subjects who had the defective gene, they found that 30 family members also had the defective gene, and each of them suffered from herniated disks.
-> Yes this statement clearly falls in line with the reasoning used and it is better than the previous one.
D. Another team of researchers examined a different group of 100 people who suffered from herniated disks, and they found that none of them had the defective gene.
-> This also weakens the reasoning.
E. When the researchers examined the family of one of the subjects who did not suffer from herniated disks, they found 30 family members who did not have the defective gene, and 20
-> Eliminating because of incomplete option.
