Which of the following sentences correctly uses an inverted conditional structure to express a hypothetical situation without the word 'if'?

A Had I known about the changes, I would have informed you immediately.
B Should I know about the changes, I would inform you immediately.
C Were I to know about the changes, I would have informed you immediately.
D If I had known about the changes, I would inform you immediately.

✓ Correct Answer: Option A

Option A correctly uses an inverted conditional for a past hypothetical situation (third conditional): 'Had + subject + past participle'. Option B uses inversion for a future/present hypothetical ('Should + subject + base verb'). Option C mixes tenses incorrectly. Option D is a standard 'if' clause.
