Answer:
Option (A)
Explanation:
Fungus are the unicellular eukaryotic living organisms that are so small that it cannot be seen with our naked eye. It plays a significant role in decomposing the dead plants, animals, and other organic matters. They are present in both terrestrial as well as the aquatic environment.
Fungus are most closely related to the animals, because they both have similar characteristics.
Fungus cannot prepare their own food like animals and they are considered to be heterotrophic. They can reproduce by the means of spores and their cells are comprised of nuclei with various numbers of chromosomes. These are the first unicellular organisms on earth from which the evolutionary processes has taken place and formed the present day complex multi-cellular organisms.
Thus, the correct answer is option (A).
The closest relatives of fungi are thought to be the ANIMALS (Option A).
In recent years, it has been estimated that ancestral fungi split from animals approximately 1.540 billion years ago.
Moreover, ancestral plants split from animals approximately 1.550 billion years ago.
In consequence, it has been proposed that fungi are more closely related to animals than to plants (i.e., fungi and animals share a more recent common ancestor with each other than with plants).
In conclusion, the closest relatives of fungi are thought to be the ANIMALS (Option A).
