<h2>B) is the correct option </h2>

Explanation:

  • Succinate dehydrogenase is the smallest component of electron transport chain and consists of four different subunits including FAD, 3 Fe-S centers
  • It catalyzes oxidation of succinate to fumarate and electrons released transferred to ubiquinone
  • Succinate dehydogenase transfer electrons from succinate to ubiquinone via FADH2 thus this complex directly links tricarboxylic acid cycle to electron transport chain
  • Activity of succinate dehydrogenase is inhibited by malonate which is a competitive inhibitor as a result oxidation of succinate to fumarate will not occur and hence concentration of fumarate will decrease

Misha Larkins [42]

The main disadvantage of growing a potato crop with few variations may be the loss of yield in a changing environment. It is a consequence of artificial selection.

<h3>What is artificial selection?</h3>

Artificial selection refers to the mating process made for humans in order to select crops and animals' progeny with desired traits.

The main subject of concern in artificial selection is the loss of valuable genetic variability.

In this case, artificial selection may lead to the potato crops being unresponsive to challenging environments.
