-
Sir Di-esel invented it
A
Correct answer
Explanation
The diesel engine is named after its inventor, Rudolf Diesel, a German engineer who developed the engine in the 1890s. Diesel patented his compression-ignition engine design in the 1890s, and the engine was subsequently named after him, similar to how the diesel fuel itself is named for the engine it powers. This naming convention follows the common practice of naming inventions after their creators.
