Which one among the following statements about an adjournment motion in the Parliament of India is not correct?

Option (c) is incorrect. An adjournment motion is introduced in Parliament to draw the attention of the House to a definite matter of urgent public importance, and it interrupts the normal business of the House — making it an extraordinary procedure (options a and b are correct). The Speaker/Chair has absolute discretion to admit or refuse consent for moving an adjournment motion (option d is correct). However, an adjournment motion cannot be invoked on matters that fall within the jurisdiction of a State Government; it must relate to matters of urgent public importance that are within the responsibility of the Central Government. Hence, statement (c) is not correct.
