And Reason are true and Reason is the correct explanation of the Assertion.
b)If both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.
c)If Assertion is true but Reason is false.
d)If both Assertion and Reason are false.

The correct answer is b) If both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.

While it is true that holophytic protistans are important phytoplanktons and contribute a significant amount to photosynthesis, the reason given for this statement is not entirely correct. Holophytic protistans do not lack chemosynthetic nutrition, as they are not capable of chemosynthesis at all. They rely solely on photosynthesis for their energy needs, and utilize inorganic compounds such as carbon dioxide and water as their sources of electrons and protons. Therefore, while both the Assertion and Reason are true, the Reason does not explain the Assertion correctly.
