Correct option is D
Option (d) contains an error.
Explanation:
The phrase "will have been being arranged" is grammatically incorrect and unnecessarily complex. This form — future perfect continuous passive — is rarely used and stylistically awkward. Instead, the correct construction should be:
“ all will have been arranged” — future perfect passive
Grammatical Rule Used:
· Future Perfect Passive Voice = will have been + past participle
· Correct: “will have been arranged”
· Wrong: “will have been being arranged”
Example:
Incorrect: The work will have been being completed by then.
Correct: The work will have been completed by then.
Information Booster: Passive voice should not be layered with continuous tenses unless absolutely necessary due to complexity and awkwardness.
