A review of our answer choices shows a split in verb forms: has/have and is/are. There is also a split in the use of creating a new independent clause or using a relative clause.
Let's start by looking at the portion of the sentence that is not underlined and thus it cannot be changed. "The Turritellenplatte of Ermingen, a type of rock, is a protected natural monument." The subject is "the Turritellenplatte of Ermingen" and the verb is "is." "Is" is the present tense third-person singular of "be," so our subject is singular.
The first portion of the sentence uses two verbs for the subject "the Turritellenplatte of Ermingen." The second verb must also be a present tense third-person singular form. "Has" is the present tense third-person singular, and "have" is present tense third-person plural. Options B and C use "have," so they cannot be the correct answers.
Some answer choices use the phrase "that is/are of interest to" instead of using "that interest." The unnecessary use of a "be" verb makes these sentences wordy. Options A and D cannot be the best answers.
Now, let's look at the they/who issue. It is not wrong to create a new sentence using the conjunction "and" and the pronoun "they." It is also not wrong to create a relative clause using "who." It is more concise to use "who." Some could even argue that the pronoun "they" does not have a clear antecedent and that it could be either the geologists and the paleontologists or the fossils. However, the fossils cannot "determine" anything on their own, so the antecedent cannot be that unclear. Since we should practice the principle of concision when possible, the options that create a second independent clause should be eliminated. Options A and D cannot be the best answers.
Should "has" or "have" be used with "who"? It depends on the noun "who" is modifying. In this case, geologists and paleontologists are plural, so the plural verb should be used. "Who have" is correct. Option B cannot be the best answer.
We have successfully eliminated four answer choices. Option E is the best answer.

I have selected A between A and E because 'who' is referring to only paleontologists but the intended meaning is both paleontologists and geologists have determined together. In fact, usage of they was clear as there was no ambiguity for the antecedent. The usage of , who is similar to usage of , which, isn't it?
Thoughts anyone?
