Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): During aerobic respiration, the inner mitochondrial membrane is impermeable to the NADH produced in the cytoplasm during glycolysis. 

Reason (R): Special shuttle systems, such as the Malate-Aspartate shuttle or Glycerol-3-Phosphate shuttle, are required to transport the reducing equivalents (electrons) from cytosolic NADH into the mitochondrial matrix.

In the light of the above statements, choose the correct answer from the options given below:

Q. Assertion (A):Thermotherapy combined with meristem (shoot-tip) culture is more effective than either method alone for eliminating certain plant viruses.

Reason (R): Some viruses such as Potato virus S (PVS) and Potato virus X (PVX) can only be eliminated when heat treatment is followed by shoot-tip culture, and larger shoot tips taken from heat-treated plants show better survival.
