<h2>Answer:</h2>
Option B is correct.
B. aerobic autotroph
<h3>Explanation:</h3>
Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis).
So, if a particular single-celled organism uses radiant energy to fix carbon as sugars and generates ATP by breaking down sugars through a process that uses oxygen, then it will be an
aerobic autotroph.
