Correct Option
An adjournment motion is a procedural device used in the Lok Sabha to draw the attention of the House to a definite matter of urgent public importance. It involves interrupting the normal business of the House for a discussion on the specified matter. The admission of an adjournment motion implies an element of censure against the government, and if accepted, it leads to a dedicated discussion lasting at least two and a half hours. This motion is not permitted in the Rajya Sabha.
Incorrect Options
Option 2: To let opposition members collect information from the ministers.
This describes the primary purpose of the Question Hour, where members ask questions to ministers on various aspects of administration and policy. It is not related to an adjournment motion.
Option 3: To allow a reduction of specific amount in demand for grant.
This is the purpose of a Cut Motion, which is moved during the discussion on Demands for Grants in the budget session. Cut motions aim to reduce the amount of a demand for grant and can be of three types: policy cut, economy cut, or token cut.
Option 4: To postpone the proceedings to check the inappropriate or violent behaviour on the part of some members.
Maintaining order and decorum in the House, including addressing inappropriate or violent behaviour, is primarily the responsibility of the Presiding Officer (Speaker in Lok Sabha, Chairperson in Rajya Sabha). While proceedings might be adjourned due to disorder, an adjournment motion itself is not the mechanism for this purpose; rather, it is a substantive motion to discuss an urgent public matter.
