Answer: Option A

Accounting principles are developed to ensure that financial statements are reliable, practical, and useful for decision-making.

These principles are not based on personal opinions or arbitrary choices but are guided by practicability, meaning they should be easy to apply and suitable in real business situations.

Convenience in recording is not a valid basis, as accounting focuses on accuracy and usefulness rather than mere ease.

Therefore, accounting principles are primarily based on practicability.

Hence, the correct answer is Practicability.
