Which feature enables adding conditional logic to forms in Power Apps?

Business Rules is the feature that enables adding conditional logic to forms in Power Apps. Business Rules allow you to create logic and validation without writing any code. This is particularly valuable for users who may not have a technical background, as it provides a user-friendly interface for defining conditions and actions based on the data in your application.

With Business Rules, you can set conditions that trigger specific actions on form fields, such as showing or hiding fields, enabling or disabling inputs, or setting field values based on user interactions or data entered. This functionality is essential for guiding users through forms dynamically, ensuring that they see only the relevant fields based on their previous responses, and improving the overall user experience.

The other options serve different purposes: Power Automate is utilized for workflow automation; Formulas allow for calculations and data manipulations within app elements but do not inherently add conditional logic in the same manner; Power Query is used for data transformation and preparation, not specifically for manipulating form behavior.
