b) as an alternative to dangerous candles.
c) to prove that electricity was affordable.
d) to show that he was a talented engineer.

Explanation:

Edward Hibberd Johnson created Christmas lights as an alternative to dangerous candles (which were used to decorate Christmas trees and posed fire hazards). Option A is incorrect as there's no major historical record of it being a gift for Queen Victoria in that context. Option C is off - topic as the main aim wasn't to prove electricity's affordability. Option D is also incorrect as the purpose wasn't to show his engineering talent but to provide a safer decoration option.

Answer:

B. as an alternative to dangerous candles
