The basic structure theory of the Constitution of India implies that certain features of the Constitution are so essential to it that they cannot be abrogated.

According to the basic structure doctrine, which has been established by judicial interpretation, there are certain fundamental principles and features of the Constitution that form its core and cannot be altered or amended in a manner that would destroy or undermine its basic structure. These principles and features include:

1. Supremacy of the Constitution: The Constitution is the supreme law of the land, and any legislation or action inconsistent with its provisions can be struck down as unconstitutional.

2. Separation of powers: The Constitution establishes a system of separation of powers among the legislature, executive, and judiciary to ensure a system of checks and balances.

3. Federalism: The distribution of powers between the central government and the state governments is a fundamental feature of the Constitution.

4. Rule of law: The Constitution upholds the principles of equality before the law, protection of fundamental rights, and adherence to due process.

5. Judicial review: The power of the judiciary to review the constitutionality of laws and executive actions is an integral part of the Constitution.

The basic structure doctrine provides a safeguard against any amendment or alteration of the Constitution that would undermine these essential features. While the Constitution can be amended, the basic structure cannot be amended or abrogated.

Therefore, the correct statement regarding the basic structure theory of the Constitution of India is:

Certain features of the Constitution are so essential to it that they cannot be abrogated.
