The correct answer is Verify the identity of the individual by other means because it is essential to confirm identities outside the platform to prevent incidents of social engineering. Even if there are mutual friends and related posts, these can be faked. Direct confirmation with the actual coworker or through internal directories would ensure the person is legitimate. Accepting the friend request immediately is incorrect because it assumes the profile is genuine without verification. Ignoring the request might be safe but does not actively address a potential impersonation issue. Blocking the profile could be a hasty decision without proper verification, as it could actually be a legitimate coworker.
