Explanation:

- If you had consulted me, I would have advised you.

- This is correct because the sentence is in the past perfect conditional structure. "Would have" should be followed by the past participle form of the verb, which is "advised."

- If you had consulted me, I would have advising you.

- Incorrect as "advising" is the present participle, unsuitable here.

- If you had consulted me, I would have advises you.

- Incorrect as "advises" is the third person singular present form, not fitting the structure.

- If you had consulted me, I would have advise you.

- Incorrect because "advise" is the base form of the verb and not the past participle needed here.

- Correct Answer: Option 3 - advised
