Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Assertion (A): Treating explants with sodium hypochlorite is done in plant tissue culture to sterilize them, and to remove surface pathogens that may be present on plant tissues, preventing microbial contamination during in vitro cultivation.
Reason (R): Sodium hypochlorite, although used for sterilisation, is not used for acclimating regenerated plants. Acclimatization involves preparing the plants for transfer to soil, through regulating environmental conditions like humidity.
Explanation: The assertion is correct, but the reason is false, making (C) the right choice.
