D. mutation
The question was asked in semester exam.
Question is from Biotechnology Applications in section Biotechnology and its Applications of Biology – Class 12
Right answer is B. antisense PG
For explanation: PG stands for an enzyme called polygalacturonase which is responsible for pectin degradation leading to early ripening. Antisense PG inhibits the formation of polygalacturonase thus delaying the process of ripening.
