Which of the following actions would be considered tampering with physical evidence?

Tampering with physical evidence involves altering, concealing, or destroying evidence with the intention of preventing it from being used in an investigation or legal proceeding. The act of tampering undermines the integrity of the judicial process and can obstruct justice. By altering or concealing evidence, an individual not only interferes with law enforcement's ability to perform its duties but also potentially affects the outcome of a legal case.

In contrast, reporting evidence to authorities, providing evidence for criminal cases, and documenting evidence properly are all actions that support law enforcement and the legal process. These actions are integral to ensuring that evidence is preserved, accurately represented, and utilized correctly within the system, promoting transparency and accountability. Therefore, the option that aligns with tampering activities is indeed the one pertaining to altering or concealing evidence.
