Explanation:

- In India, an individual who is not a member of Parliament can indeed be appointed as a Minister by the President.

- According to Article 75(5) of the Indian Constitution, such a person must become a member of either the Lok Sabha or the Rajya Sabha within a period of six months from the date of their appointment.

- Option 1: 9 months - This is incorrect, as the timeframe is shorter.

- Option 2: 3 months - This is incorrect, as it does not align with constitutional provisions.

- Option 3: 12 months - This is incorrect, as it exceeds the constitutionally allowed period.

- Option 4: 6 months - This is the correct answer. The individual must be elected or appointed as a member of Parliament within six months.
