Solution (By Examveda Team)

In the sentence, "The electric light bulb was invented by Edison," the past simple tense "was invented" is used to describe a specific action that occurred in the past – the invention of the electric light bulb by Edison.

The correct form for the sentence is "The electric light bulb was invented by Edison."

The other options are not suitable because they do not use the correct verb form or tense:

Option A: invented
This option uses the past participle "invented," but it is not in the correct form to complete the sentence.

Option B: invents
This option uses the present tense "invents," which is not appropriate for describing a past action.

Option C: is invented
This option uses the present simple passive tense "is invented," but it does not accurately convey the past action.

Therefore, the correct answer is Option D: was invented.
