D Correct answer
Explanation

Humphry Davy invented the first electric light in 1802 (the electric arc lamp), which was the precursor to the incandescent bulb. While Edison is credited with the practical long-lasting incandescent bulb (1879), Davy's earlier invention established the principle. Lord Kelvin, Ida Hyde, and Huygens are not associated with electric lighting inventions.
