The correct answer is option 4: Residuary List - Education.

In India, the Constitution divides legislative powers between the central government and state governments. This division is achieved through three lists: the Union List, the State List, and the Concurrent List.

The Union List includes subjects on which only the central government can make laws. Some examples of subjects in the Union List are defense, foreign affairs, and atomic energy.

The State List includes subjects on which only the state governments can make laws. Agriculture is one such subject in the State List, as it is primarily within the jurisdiction of the state governments.

The Concurrent List includes subjects on which both the central and state governments can make laws. One example of a subject in the Concurrent List is marriage, as both the central and state governments can enact laws related to marriage.

The Residuary List includes subjects which are not mentioned in any of the three lists. In other words, it covers areas that are not within the jurisdiction of either the central or state governments. However, education is not included in the Residuary List. Education falls under the Concurrent List, which means both the central and state governments have the authority to make laws related to education.
