C. Both A and B
Explicación
## Step 1This problem is about diagnosing the potential causes of a vehicle's dead battery after sitting overnight. The two technicians, A and B, propose two different causes.## Step 2Technician A suggests that an excessive parasitic draw could be the cause. Parasitic draw refers to the electrical components that continue to draw power from the battery even when the engine is off. This can lead to the battery being drained, causing the vehicle to have a dead battery.## Step 3Technician B suggests that a battery with an incorrect Cold Cranking Amps (CCA) rating could be the cause. The CCA is a measure of the battery's ability to start the engine in cold temperatures. If the battery's CCA rating is too low, it may not be able to provide enough power to start the engine, leading to the vehicle having a dead battery.## Step 4Both Technician A and Technician B are correct in their assessments. An excessive parasitic draw can indeed cause a vehicle's battery to be drained, leading to a dead battery. Similarly, a battery with an incorrect CCA rating can also cause the vehicle to have a dead battery.
