Solution

The correct option is B RFLP analysis
The first method for finding out genetics used for DNA profiling involved RFLP (Restriction fragment length polymorphism) analysis. DNA is collected from cells (sample) and cut into small pieces using a restriction enzyme. The fragments are then separated on the basis of size using gel electrophoresis. Therefore, the correct answer is option B.
