Explanation:

Both statements 2&3 are correct.

Recently, the Supreme Court asked if the States of Telangana, Andhra Pradesh and Karnataka could amicably settle their quarrel over the allocation of the Krishna river water. Krishna River originates near Mahabaleshwar (Satara) in Maharashtra. 

• It is the second biggest river in peninsular India after the Godavari River.

Article 262 of the Constitution provides for the adjudication of inter state water disputes. 

• The Parliament has enacted two laws, the River Boards Act (1956) and the Inter-State Water Disputes Act (1956). 

The Inter-State Water Disputes Act empowers the Central government to set up an ad hoc tribunal for the adjudication of a dispute between two or more states in relation to the waters of an inter-state river or river valley.

• Neither the Supreme Court nor any other court is to have jurisdiction in respect of any water dispute which may be referred to such a tribunal under this Act. 

Hence both statement 2&3 are correct.
