Based on the DNA diagram, which of the five children might be related to the missing child?

Our genes consist of DNA molecules. DNA fingerprinting allows the detection of DNA

fragment patterns in different people. In this process, enzymes are used to "cut" a person’s DNA into pieces. The length of these fragments differs from person to person and, therefore, there is little chance that two or more people will produce the same pattern. The DNA fragments of different people can be readily compared. DNA fingerprinting has many applications in law enforcement, medicine, and other areas.

The diagram below lists simulations of the DNA "fingerprint" band patterns for six individuals―a missing child and five young people who have the missing child’s physical characteristics.
