The correct answer is D.
Section 3 of the Constitution (Forty-fourth Amendment) Act, 1978 sought to amend Article 22(4) of the Constitution. The amendment aimed to reduce the maximum period for which a person may be detained under a preventive detention law without obtaining the opinion of an Advisory Board from three months to two months. However, this specific provision (Section 3 of the 44th Amendment Act) was never brought into force by the government through a notification in the Official Gazette.
As a result, the original text of Article 22(4), which allows preventive detention for a period longer than three months only if an Advisory Board has reported sufficient cause before the expiration of the said three months, remains in effect. Amendments related to Articles 20(1), 20(2), and 21 (specifically the addition of Article 21A by the 86th Amendment) have been duly enforced.
