Answer 2

"Thomas Edison" is well known as a "great inventor". However, he was also a "fantastic improver" is the correct answer.

Option (a);

EXPLANATION:

Thomas Edison is believed to be a landmark of inventions. Light bulb was already invented by 'Humphry Davy' around forty years ago even when Edison was born. But those could not be used domestically at homes in a safer way. Edison invented a practical glowing light bulb for the first time.

Many people had worked and created some of the other forms of lighting. But nothing was such that could be used at homes practically. So, Edison developed 'incandescent light bulb' that was safe, practical and economical.
