The correct answer is option B, that is, Ciliophora.
Ciliophora is the term used for the phylum usually known as the ciliates. Ciliates are the most complex of cells, exhibiting an elaborate cytoskeleton, cilia, two distinct types of nuclei. Ciliates are single-celled species, which at a certain phase of their life cycle, possesses cilia, that is, short hair-like projections used for food gathering and locomotion.
<h2>Answer:</h2>
The option A is the correct option. The fungi share a mutualistic association with the trees.
<h3>Explanation:</h3>
Mutualism or interspecific cooperation is the way two organisms of different species exist in a relationship in which each individual fitness benefits from the activity of the other. And in this case, both plant and fungi are benefited by each other. The plant provides food and habitat for the living of fungi and fungi, in turn, decompose dead organic matter to provide simple compounds to plants.
While in commensalism only one either plant or fungi can be benefited. And it is also not a parasitic interaction.
Light speed in water is 2.25 times 10^5 m/s so the index of refraction is higher than the index of refraction of light in a vacuum which is 1.0. (speed in vacuum for light is 300,000 km/s)
Index of refraction of light in water is 3.0 time 10^5 m/s divided by 2.25 times 10^5 m/s = 1.33.
Hope this is what you wanted.
