Answer

Brief Explanations:

In the United States, vehicles produced after 1996 (OBD - II compliant) are required to monitor the efficiency of the catalytic converter. Catalyst monitoring is indeed accomplished using multiple oxygen sensors (up - stream and down - stream oxygen sensors to compare oxygen levels before and after the catalytic converter). So both statements are correct.

Answer:

c. Both Technician A and Technician B
