Which of the following human vectors are most likely to be part of a voice call-based attack?

Pretexting and impersonation are common elements in voice call–based attacks. Watering hole attacks leverage commonly visited websites, disinformation is when incorrect information is intentionally provided to change public opinion and could be part of a voice campaign but is not the most common element, and business email compromise (BEC) requires an email to be used, not a voice call.
