Question

there are two basic configurations used to monitor the vehicles tire pressures:
and
a. flat, rough
b. direct, indirect
c. high, low
d. high band, low band

Explanation:

Direct tire - pressure monitoring systems use sensors to directly measure tire pressure. Indirect systems use the vehicle's anti - lock braking system (ABS) sensors to infer tire pressure changes based on wheel rotation differences. Options a (flat/rough) are about road conditions, not monitoring configurations. Option c (high/low) is about pressure levels, not monitoring types. Option d (high - band/low - band) is not relevant to tire - pressure monitoring configurations.

Answer:

B. Direct, indirect
