(D) To search the house address of a relative on the Internet.
Genetics and Genomics uses data science to understand DNA's impact on health, analyze drug/disease reactions, and find individual biological connections — not for searching personal addresses.
The passage clearly states that data science applications in Genetics & Genomics include: understanding genetic issues, reactions to drugs and diseases, and individual genome/biological connections. Searching a house address is an everyday internet activity unrelated to genetics. Examiners expect students to identify the odd one out using the passage.
