• A. Genetic Engineering
• B. DNA Profiling
• C. Genetically Modified Organism (GMO)
• D. Polyploidy

Answer: (B)

DNA profiling is the method used to identify an individual based on their unique arrangement of DNA bases. By exposing DNA to molecular probes, scientists detect specific sequences and build a distinctive pattern of variable regions that acts like a fingerprint for that person. This pattern is unique to each individual (except identical twins) because the number and order of repeats at key loci vary among people. The other terms describe different concepts: genetic engineering involves altering DNA to create modified traits, a GMO is an organism carrying such modifications, and polyploidy refers to having extra chromosome sets rather than an identification method.
