DNA profiles of the child and three individuals 1, 2 and 3 who claim to be the parents of the child are given below. Select the option that shows the correct actual parent/parents of the child.

The correct option is Individual 1 and 3.

Logical Explanation:
DNA profiling (or DNA fingerprinting) is a forensic technique used to determine parentage. A child inherits exactly half of their genetic material from the biological mother and the other half from the biological father.
Therefore, in a gel electrophoresis DNA profile, every single band present in the child's profile must align with a corresponding band in either the mother's profile or the father's profile.

$$\text{Child's DNA Bands}\subseteq (\text{Parent 1 Bands}\cup \text{Parent 2 Bands})$$

By analyzing the gel electrophoresis lanes from top to bottom, we can trace the origin of each band in the child's lane (marked X):
1. 1^st band (topmost): Aligns perfectly with a band in Individual 1.
2. 2^nd band: Aligns perfectly with a band in Individual 3.
3. 3^rd band: Aligns perfectly with a band in Individual 1.
4. 4^th band: Aligns perfectly with a band in Individual 3.
5. 5^th band: Aligns perfectly with a band in Individual 1.
6. 6^th band: Aligns perfectly with a band in Individual 1.
7. 7^th band: Aligns perfectly with a band in Individual 3.
8. 8^th band (bottommost): Aligns perfectly with a band in Individual 1.

Since every single one of the child's 8 DNA bands matches a band from either Individual 1 or Individual 3, we can conclude that Individual 1 and 3 are the actual biological parents of the child.
