The Parliament of India exercises control over the functions of the Council of Ministers through Adjournment motion, Question hour, and Supplementary questions.

Option 1 - Adjournment motion is a tool used by the Parliament to discuss a matter of urgent public importance. It leads to cessation of the regular business of the House to discuss the matter raised in the motion. So, it is one important tool through which Parliament exercises control.

Option 2 - Question hour is the first hour of a sitting session of India`s Lok Sabha devoted to questions that Members of Parliament raise about any aspect of administrative activity. So, this is another way Parliament can exercise control over the Council of Ministers.

Option 3 - Supplementary questions are those that are asked for further clarification or information about a response to a starred question. It enhances the ability of Parliament to keep a check, making it another tool of control.

Thus, option 4 is the correct answer as Parliament uses all three (Adjournment motion, Question hour, and Supplementary questions) to control the Council of Ministers.
