Explanation:

The subject of the sentence is "The Arrhenius equation", which is singular. The verb should agree with the subject in number. "Remains" is the third - person singular form of the verb "remain", which is appropriate here as it describes a present - day fact about the equation. "Remain" is plural, "have remained" is plural and in present perfect tense which is not required, and "are remaining" is also plural and in present continuous tense which is not the correct tense for this general truth statement.
