Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The net gain of ATP in aerobic respiration is significantly higher than in fermentation.
Reason (R): In fermentation, glucose is only partially oxidized, and the NADH produced in glycolysis is not utilized to generate ATP via the Electron Transport Chain.
In the light of the above statements, choose the correct answer from the options given below:

#Botany
  1. Both (A) and (R) are correct and (R) is the correct explanation of (A).
  2. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
  3. (A) is correct but (R) is incorrect.
  4. (A) is incorrect but (R) is correct.

#Plant Biotechnology

Q. Statement I: In the cybrid approach, iodoacetate is used to inactivate the nuclei of the recipient strain (Parent A). 
Statement II: Irradiation is used to inactivate the nuclei of the donor strain (Parent B) to ensure only its cytoplasm is transferred.

Q. Statement I: Fusing tomato protoplasts with irradiated Solanum acaule protoplasts produced plants that were morphologically identical to Solanum acaule. 
Statement II: The resulting tomato regenerants exhibited Cytoplasmic Male Sterility (CMS), which was inherited maternally.
