Option A) SessionId - This option is incorrect because SessionId is a property that returns the unique identifier for the session, but it does not set the local identifier.
Option B) LCID - This option is correct because LCID is the property that is used to set the local identifier. LCID stands for Locale ID, and it represents the language and regional settings for the session.
