Is this a default functionality of the Lifecycle Manager (LCM) module?

Defining an application is not a default functionality of the Lifecycle Manager (LCM) module. Application definitions are typically part of the core IdentityIQ platform and are managed through the IdentityIQ Administration module, not Lifecycle Manager. LCM is primarily focused on managing identity lifecycle events, such as onboarding (Joiner), role changes (Mover), and offboarding (Leaver).

Therefore, the correct answer is B. No.
