The correct answer is D. All of above.

Under the Citizenship Act of 1955, a person can acquire Indian citizenship by birth, descent, registration, or naturalization.

• A person born in India on or after 26th January, 1950 is a citizen of India by birth.
• A person born outside India on or after 26th January, 1950 is a citizen of India by descent if his father or mother is a citizen of India at the time of his birth.
• A person who is not a citizen of India but who has been ordinarily resident in India for not less than five years immediately preceding the date of his application may be registered as a citizen of India if he satisfies the following conditions:
  • He is a person of good character;
  • He has resided in India for not less than five years immediately preceding the date of his application;
  • He intends to reside in India permanently;
  • He has an adequate knowledge of Hindi or English;
  • He has an adequate knowledge of the Constitution of India; and
  • He has taken an oath or affirmation of allegiance to India.
• A person who is not a citizen of India but who has been ordinarily resident in India for not less than 11 years immediately preceding the date of his application may be naturalized as a citizen of India if he satisfies the following conditions:
  • He is a person of good character;
  • He has resided in India for not less than 11 years immediately preceding the date of his application;
  • He intends to reside in India permanently;
  • He has an adequate knowledge of Hindi or English;
  • He has an adequate knowledge of the Constitution of India; and
  • He has taken an oath or affirmation of allegiance to India.

In addition to the above, a person may also acquire Indian citizenship by incorporation of territory. This means that if a territory is incorporated into India, the people of that territory will automatically become Indian citizens.
