Which of the control lights visible in the illustration upon lighting up, requires you to stop immediately and rectify the fault?

The illustration shows three warning lights: A - orange letters ABS in a circle, B - a red oil can with a drop, C - an orange fuel pump. When light B comes on, showing that the oil pressure is too low, you must stop immediately and fix the fault - answer B. The ABS warning light (A) allows you to drive carefully to a garage, because the normal brakes still work, and the fuel reserve light (C) only tells you to look for a petrol station.

The colour of the light tells you how urgent the problem is: red means danger and the need to react immediately, orange - a fault or a warning with which you can carefully continue driving. The red oil can comes on when the oil pressure in the engine drops - because the oil level is too low, the pump is damaged or the filter is blocked. Without pressure, the oil does not reach the crankshaft bearings and the camshafts; metal rubs against metal and the engine can seize within a few minutes. That is why you pull over in a safe place, switch off the engine, check the oil level with the dipstick and top it up; if this does not help, you call for roadside assistance. The Road Traffic Act requires a vehicle to be maintained in such a way that using it does not endanger safety.
