The answer is: C
Explanation
The correct option is C: Article 22.
This article deals with the protection against arrest and detention in certain cases. It states that no person who is arrested shall be detained in custody without being informed, as soon as may be, of the grounds for such arrest nor shall he be denied the right to consult, and to be defended by, a legal practitioner of his choice. It also lays down the conditions and limitations for preventive detention, such as the maximum period of detention, the right to make a representation against the order, and the constitution of an advisory board to review the detention. Article 22A does not exist in the Indian Constitution. Article 21 deals with the right to life and personal liberty, and Article 21A deals with the right to education.
