The most adequate way to demonstrate the problem is in the provided sentence:
D). The comma is unnecessary between clauses.
Comma
In the supplied sentence, the two clauses are associated via a coordinating conjunction 'and' they are free and independent in their character traits.
Since a comma is employed either to ensure a pause among clauses or sentence or to segregate them to keep the meaning precise, the comma in the provided sentence is unnecessary due to the presence of conjunction. Therefore, it must be removed.
Thus, option D illustrates the correct answer.
