In an engine lubrication system ‘Valve train components’ receive oil.
Option: A
Step-by-step explanation:
The ‘valve train components’ are the last to get oil and first to suffer from a insufficient of oil or oil pressure. First, the oil is passed through the ‘oil filter’ from the ‘oil pump’ and then it goes into a drilled hole which is intersected with a drilled main oil gallery. Now the block head allows the oil that came through the passages drilled to the main bearing and cam bearing from the main oil gallery. Then at last, the oil is received by the valve train components.
