Considering the original judgment presented in the question, letter D (Edit function activation settings) would be the most pertinent choice, since the other options would not directly apply to the function's time limitation.
However, it is important to note that the actual configuration of time limitations for privileged roles must be performed through Azure AD Privileged Identity Management (PIM) policies to ensure secure use and required compliance of privileged roles. Therefore, although D may be the most detailed option based on the logic of the question, the specific configuration of the time limitation must be performed in PIM.
