The correct answer is Neither A nor B. therfore no technician is correct neither connecting rods nor the rod bearings says technician is right.
As the piston moves inside the cylinder, the connecting point between the second end of the rod and the crankshaft is sufficiently offset from the longitudinal axis to enhance engine torque and horsepower. Connecting rods can be made of a wide range of materials, including carbon steel, cast iron with spheroidized graphite, iron base sintered metal, and micro-alloyed steel. The connecting rods used in mass-produced car engines are typically constructed of steel.The crankshaft and connecting rod are held in position while rotating by an engine rod bearing, which is a split-sleeve type bearing (meaning it has two distinct semicircular half or shelves).
