The appropriate responsibility of < isif > isconditional presentation. Evaluating a Boolean already present inpdictand choosing between different pieces of markup is exactly the intended ISML use case.
Salesforce ' s official < isif > documentation is explicit that < isif > , < iselseif > , and < iselse > containno business logic; they provide conditional visualization of data. The condition can use Pipeline Dictionary variables and other expressions that resolve to Boolean behavior.
Option B therefore violates the separation of concerns used by SFRA. Complex business rules should be computed before template rendering—typically in controllers, helpers, models, or other server-side modules—and only their resulting data should be passed to ISML. Option C is also incorrect because redirecting a request is controller responsibility. A template should not control HTTP routing or authentication flow.
The supplied question ' s correct use is consequently showing a different < div > based on an already computed Boolean.
