Answer 1

The correct choice is (a) Oil pan

For explanation I would say: The crankcase is that part of the engine which supports and encloses the crankshaft and camshaft. It provides a reservoir for the lubricating oil of the engine. It also serves as a mounting unit for such accessories as the oil pump, oil filter, generator, starting motor and ignition components. The upper portion of the crankcase is usually integral with cylinder block. The lower part is commonly known as oil pan and usually made of cast iron or cast aluminium.
