Which two categories describe conventional piston-driven engines?

The engine types discussed are inline and V-type

The engine types discussed are horizontally opposed and radial

Conventional piston-driven engines in aviation are typically described by how their cylinders are arranged, with two classic layouts: radial and horizontally opposed. The radial design stacks cylinders around the crankcase in a circle, which aids cooling and power delivery for the engine’s size. The horizontally opposed (flat) design places cylinders on opposite sides of the crankshaft, giving a compact, smooth, and low-profile package that fits neatly in many airframes. These two configurations are the traditional, widely recognized categories for piston-driven aircraft engines.

The other options mix in configurations that aren’t representative of conventional piston-driven aircraft engines in the same way. Wankel/rotary engines are not piston-driven, and turboprops are turbine-based propulsion. Inline and V-type pistons do exist and are common in cars, but they’re not the two hallmark categories emphasized for conventional aircraft piston engines.
