Answer: A, C

Explanation:

To build a responsive application capable of responding to touch events and executed on stateful clients, the developer should use technologies that support modern web standards, responsive design, and touch interactions. The two technologies that meet these requirements are Aura Components and Lightning Web Components.

Option A: Aura Components

Aura Components are part of the Lightning Component Framework and are designed to build dynamic web applications for mobile and desktop devices. They support responsive design and can handle touch events, making them suitable for building applications that run on stateful clients.

Reference: "The Aura Components programming model is designed to support developing responsive applications for mobile and desktop devices."

Lightning Web Components (LWC) is a modern framework built on web standards. LWC components are lightweight and deliver exceptional performance. They support responsive design and can handle touch events, making them ideal for stateful clients.

Reference: "Lightning web components are custom HTML elements built using HTML and modern JavaScript." "Because Lightning web components are based on web standards, they are inherently efficient and deliver exceptional performance."

Why Other Options Are Incorrect:

Option B: Visualforce Pages

Visualforce is a server-side framework that doesn’t fully support responsive design or touch events natively. While you can make Visualforce pages responsive using custom code, it doesn’t provide built-in support for touch events as effectively as Aura Components or LWC.

Reference: "Visualforce is a component-based user interface framework for the Force.com platform."

― Visualforce Developer Guide Option D: Visualforce Components

Visualforce Components are custom components within the Visualforce framework. They inherit the same limitations as Visualforce Pages regarding responsiveness and touch support.

Reference: "A Visualforce component is either a standard component, provided by the Visualforce framework, or a custom component that you create."
