The Constitution (98th Amendment) Bill is related to:

A) Empowering the Centre to levy and appropriate service tax
B) The constitution of the National Judicial Commission
C) Readjustment of electoral constituencies on the basis of the Population Census 2001
D) The demarcation of new boundaries between States

The correct answer is Option 2. The Constitution (Ninety-Eighth Amendment) Bill was introduced to insert Chapter IV-A into Part V of the Constitution, providing for the establishment of a National Judicial Commission (NJC).

The primary objectives of this amendment were:

• To create a body chaired by the Chief Justice of India for the appointment and transfer of judges in the higher judiciary.
• To ensure a more transparent and participatory mechanism for judicial appointments, moving away from the "collegium system."
• To establish a framework for inquiring into cases of judicial misconduct.

Regarding other options:

• Option 1 refers to the 88th Amendment Act (2003).
• Option 3 refers to the 87th Amendment Act (2003).
• Option 4 relates to Article 3 of the Constitution, not the 98th Amendment.

Therefore, Option 2 is the only correct association for the 98th Amendment Bill.
