Answer:
The correct answer is option B. "A mutation occurred in a gene found in some fungi, and the enzyme produced is able to break down lignin".
Explanation:
The unique trait of expressing lignin peroxidase that some fungi have in order to break down lignin must have being the result of natural selection. Natural selection works under the premise of "survival of the fittest", where a spontaneous mutation gives an advantageous trait to an individual that makes it more likely to survive and reproduce. In this case breaking down lignin gives some fungi the advantage of being able to feed from wood.

Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems.
<h2>Postzygotic isolation </h2>
Explanation:
In the given information of edible frog both male and female hybrids exist, but when they mate among themselves, they cannot successfully produce offspring which defines that postzygotic isolation exists between the two frog species
- Postzygotic isolation prevents the formation of fertile offspring
- Before the postzygotic isolation can happen, there must be an offspring born from a male and female of two different species
- This means there were no prezygotic isolations, such as the fitting together of the sex organs or incompatibility of the gametes or differences in mating rituals or locations, that kept the species in reproductive isolation
- The offspring of two different species known as a hybrid is not always viable
- Sometimes, they will self-abort before being born and other times, they will be sickly or weak as they develop
