  1. set display local

B Correct answer
Explanation

In Unix shells, the DISPLAY environment variable tells X-windows where to render. The setenv command (csh/tcsh) sets it with format hostname:display.screen. Option B correctly uses setenv with proper format (note: the IP in the question has a minor inconsistency but the command syntax is correct). Options A and D incorrectly use 'local' instead of an IP address. Option C uses a non-existent command.
