The relative clause "who investigated the Mars One project" modifies and identifies the noun "researchers."

1. Relevant knowledge points and concepts
- A relative clause gives more information about a noun (the antecedent or head noun).
- Relative pronouns (who, which, that) introduce these clauses; "who" specifically refers to people.
- Restrictive (defining) relative clauses narrow down which members of a noun group are meant; nonrestrictive clauses add extra information.

2. Step-by-step reasoning
- Locate the relative clause: it begins with the relative pronoun "who" and runs through "project": "who investigated the Mars One project."
- Find the noun immediately modified by that clause: the clause is attached to the preceding noun phrase "The researchers."
- Check semantic fit: "who" refers to people, so it must refer to a noun denoting people.
- Test by removing the clause: "The researchers work at MIT." This is grammatical and leaves the basic sentence intact; the clause is additional information defining which researchers are meant.

3. Intermediate analysis steps
- Head noun in the NP "The researchers who investigated the Mars One project" is "researchers."
- The clause is restrictive: it specifies which researchers (those who investigated the Mars One project).
- Agreement and meaning check: "researchers" (plural) matches the verb "work" (plural), consistent with the clause referring to those people.

4. Why the correct answer is correct
- The clause describes the people doing the investigating, so it defines "researchers." The relative pronoun "who" cannot itself be the answer (it only introduces the clause). The clause does not modify "Mars One project" (an inanimate project) nor "MIT" (the institution).

5. Why other possible nouns are incorrect
- "Mars One project": the clause states that the researchers investigated that project; it is the object of investigation, not the noun being defined.
- "MIT": functions as the workplace and is not modified by the relative clause.
- "who": is a pronoun introducing the clause, not the head noun being defined.

6. Conclusion
The noun defined by the relative clause is researchers, which matches the provided answer: researchers.
