C Correct answer
Explanation

setenv (option C) is the correct command for setting environment variables in csh and tcsh shells. printenv (B) displays variables but doesn't set them. senv (A) and setupenv (D) are not standard Unix commands. In bash/sh, the equivalent command is 'export', but setenv is the correct answer for Unix shell environments.
