What is Reginald Fessenden known for inventing?

Telephone
Radio
Snowmobile
Electric light bulb

The correct answer is: Radio

Reginald Fessenden is known for inventing the radio. Fessenden's work was important in the development of wireless telegraphy, allowing for the transmission of voice and music through radio waves. This makes options A (telephone), C (snowmobile), and D (electric light bulb) incorrect as they were all invented by different individuals and have no relation to Fessenden's work on the radio. Additionally, the radio was not the only invention Fessenden is known for, as he also contributed to the development of sonar and the superheterodyne principle.
