The Council of Ministers is collectively responsible to the Lok Sabha, a part of the Parliament, making statement 1 correct. While ministers hold office during the pleasure of the President, this is exercised on the advice of the Prime Minister, and the removal of a minister is generally a political decision based on the Prime Minister's confidence, thus statement 2 reflects this constitutional provision. The Prime Minister is constitutionally mandated to keep the President informed about the decisions of the Council of Ministers relating to the administration of the affairs of the Union and proposals for legislation, validating statement 3.
