Which passive sentence correctly includes the ‘by’ agent because the doer is specific and relevant information?

Explanation

While the ‘by’ agent phrase can often be omitted in the passive voice when the doer is unknown or unimportant, it should be included when identifying the doer adds meaningful, relevant information to the sentence, as in ‘The novel was written by a famous author.’ Omitting the agent here, as in simply ‘The novel was written,’ would leave out a detail the sentence is specifically trying to convey.
