Which statement is true regarding SAIL?

The statement that SAIL allows for a single run and deployment on different platforms is correct because SAIL (Self-Assembling Interface Layer) is specifically designed for building user interfaces in Appian applications that are platform-agnostic. This means that applications created with SAIL can run seamlessly across different devices and operating systems without requiring separate development or deployment for each platform. This cross-platform capability is one of the key advantages of using SAIL for developing interfaces, as it simplifies the development process and enhances user accessibility.

In contrast, the other statements do not accurately reflect SAIL's purpose or functionality. SAIL is not a traditional programming language but rather a declarative language for designing interfaces. It is very much involved in creating interactive user interfaces rather than being excluded from that function. Additionally, SAIL supports both dynamic and static content, allowing for a more engaging user experience. Thus, the statement about only supporting static content is also inaccurate.
