If the fundamental accounting assumptions, viz. Going Concern, Consistency and Accrual are followed in financial statements, specific disclosure is not required. If a fundamental accounting assumption is not followed, the fact should be disclosed.

Explanation:

1. Going Concern:
The going concern assumption assumes that a business entity will continue to operate indefinitely. It assumes that the entity will not be forced to liquidate its assets and cease operations in the near future. This assumption allows for the preparation of financial statements on the basis that the entity will continue to operate and meet its obligations.

2. Consistency:
The consistency assumption assumes that accounting methods and procedures should be consistent from one period to another. It ensures that financial statements from different periods are comparable and meaningful. Consistency allows users of financial statements to make meaningful comparisons between different periods and make informed decisions.

3. Accrual:
The accrual assumption assumes that financial transactions and events should be recorded in the period in which they occur, rather than when cash is received or paid. This means that revenues are recognized when earned and expenses are recognized when incurred, regardless of when cash is received or paid.

Explanation of Incorrect Options:

Option A:
- Conservatism is not a fundamental accounting assumption. It is a principle that suggests that uncertainties and risks should be recognized and recorded in a conservative manner.
- Matching is a principle that states that expenses should be matched with the revenues they help to generate. It is not a fundamental accounting assumption.
- Accrual is correct, but the other two options are incorrect.

Option B:
- Matching is incorrect as explained above.
- Consistency is correct.
- Accrual is correct, but the other two options are incorrect.

Option D:
- Entity is a fundamental accounting assumption that assumes that the business entity is separate and distinct from its owners or shareholders. This assumption allows for the identification and recording of financial transactions related to the business entity.
- Periodicity is a principle that suggests that the economic life of a business can be divided into artificial time periods for the purpose of financial reporting. It is not a fundamental accounting assumption.
- Going concern is correct, but the other two options are incorrect.

Therefore, the correct answer is option C: Going concern, Consistency, Accrual.
