Solution
The correct option is B McClintock
DNA segments that can move from place to place in the genome are called as jumping genes. Jumping genes were first discovered by Barbara McClintock and M. Rhoades as controlling elements. While working on chromosome breakage in maize, she observed that a chromosome-breaking locus could change its position within a chromosome and control the expression of gene. She named them “jumping genes”. Correct answer is C.
