Answer: (B)

Privilege and the work product doctrine shield certain attorney communications and materials from disclosure in investigations. The attorney-client privilege covers confidential exchanges between a client and their lawyer that seek or receive legal advice, so investigators generally can’t force the disclosure of those emails, notes, or conversations as long as confidentiality is maintained and the relationship is properly established. The work product doctrine protects materials created by or for counsel in anticipation of litigation—think trial plans, legal research, and, importantly, the lawyer’s mental impressions or strategy. These protections ensure that legal thinking and strategy stay confidential, encouraging candid legal guidance.

In practice, this means investigators are limited in what they can compel when these protections apply. For example, communications discussing legal advice are off-limits if kept confidential, and strategy or preparatory materials prepared by counsel are typically shielded, with exceptions only in narrow circumstances (such as waivers or cases where a crime-fraud exception might apply). Understanding these protections helps explain why some information remains confidential during investigations even as other, non-privileged facts can be examined.
