The correct answer is option 3: 44th Amendment. The right to property was originally enshrined as a Fundamental Right in the Indian Constitution under Article 19(1)(f). However, with the passage of the 44th Constitutional Amendment in 1978, the right to property was removed from the list of Fundamental Rights.

The 44th Amendment brought about significant changes to the Constitution, aimed at restoring certain provisions that had been suspended during the period of emergency in the mid-1970s. One of the key changes was the removal of the right to property as a Fundamental Right.

After the amendment, the right to property was converted into a legal right under Article 300A, which means that it is still protected but no longer a Fundamental Right. This amendment was made to strike a balance between individual rights and the need for the government to acquire property for public use.
