Answer:
C. An investigation
Explanation:
In case of presence of sufficient evidence to proceed after the initial inquiry in response to a research misconduct allegation, the next main phase is to conduct an investigation that assesses the available evidence and investigates any other evidence that might not have been found until now. The investigation is conducted under the supervision of the institutional board or committee to ensure transparency. Investigation is only initiated when there is sufficient evidence and an inquiry has been made.
