Explanation:

OSHA (Occupational Safety and Health Administration) has set a permissible exposure limit (PEL) for carbon monoxide over an 8 - hour period. According to OSHA standards, the PEL for carbon monoxide (CO) in an 8 - hour time - weighted average (TWA) is 50 ppm. This is based on the potential health risks of CO exposure, such as oxygen deprivation in the body.

Answer:

d. 50 ppm
