a) technician a
b) neither technician a nor b
c) technician b
d) both technicians a and b

Explanation:

Question 1

Biodiesel blend notation BXX: "XX" represents the percentage of biodiesel in the blend. Option A is wrong (distiller not related), C is wrong (region not denoted), D is wrong (E - diesel not what "XX" represents).

• Technician A: Coil - on - plug (COP) system removes spark plug wires, which are a source of electromagnetic interference that can disrupt computer signals. This is correct.
• Technician B: GM's three - wire COP system has an Ignition Control Module (ICM) built into the coil assembly. This is also correct. So both are correct.

Answer:

B) percentage of biodiesel contained in the blend
