Show answer & explanation
Correct answer: A
Explanation:
To change the active sentence 'They have published all the details of the invention.' into passive voice, make the object the subject, keep the present perfect tense, and add the agent.
Subject (object of active): 'All the details of the invention' becomes the subject of the passive sentence.
Tense: Present perfect 'have published' → passive form 'have been published'.
Agent: Add 'by them' to indicate who performed the action.
Final passive sentence:
All the details of the invention have been published by them.
Why the other choices are incorrect:
The publication of the details of invention was done by them. — This is wordy and uses past simple 'was done', which changes the tense and emphasis compared with the original present perfect construction.
All the details have been invented by the publishers. — This uses the verb 'invented' instead of 'published', which changes the meaning and is therefore incorrect.
All the inventions have been detailed by them. — This alters the noun phrase from 'details of the invention' to 'inventions', changing the intended meaning and making it not equivalent to the original sentence.
