Correct answer: (c) Reproductive cloning of animals
Explanation
- A
Production of biolarvicides
Biolarvicides are microbial or botanical agents against mosquito larvae (for example Bti). They are not produced by somatic cell nuclear transfer. This option is not the key.
- B
Manufacture of biodegradable plastics
Biodegradable plastics (PHA, PLA) come from fermentation or petro-substitutes, not from SCNT. This option is therefore wrong.
- C
Reproductive cloning of animals
Somatic Cell Nuclear Transfer places a somatic nucleus into an enucleated egg so a clone can develop. Dolly the sheep is the textbook animal reproductive-cloning application. That is why (c) is the official key.
- D
Production of organisms free of diseases
Disease-free organisms may be a breeding goal, but SCNT’s defining application in this question is reproductive cloning, not pathogen-free production as such. This option is not the key.
Summary. Official key is (c) Reproductive cloning of animals. SCNT is the nuclear-transfer method used to clone mammals from a body cell. Biolarvicides and bioplastics are different biotech streams. Creating disease-free stock is not the name of the technique. Dolly (1996) is the landmark SCNT clone.
