Which consequence results when lubricant supply fails concurrently with high engine load on an internal combustion engine?

💡 Explanation

Bearing seizure occurs because lubrication failure during high-load operation increases friction; frictional heat generation causes the crankshaft bearing material to exceed its melting point. This leads to thermal seizure, therefore option A, rather than injector problems or valve/gasket issues.
