Answer: Virus-free plants through micropropagation.
- A Polyploid plants with artificially doubled chromosome sets
- B Callus tissue used specifically for SCP production
- C Virus-free plants through micropropagation
- D Plants carrying deliberately induced genetic mutations
Correct answer: C. Virus-free plants through micropropagation
Explanation: Meristem culture uses shoot apical meristems which are usually virus-free; this technique is used to produce disease-free (particularly virus-free) plants on a large scale.
Different fish species occupy different feeding depths in the same pond without competing for food: Catla feeds near the surface, Rohu in the middle zone, and Mrigal or common carp at the bottom - letting a single pond support far more total fish than one species alone.
