The implicit variable available to JSP pages that may be used to access all the other implicit objects is the pageContext object.
Let's go through each option to understand why it is correct or incorrect:
Option A) page - This option is incorrect because the page object is not available as an implicit object in JSP pages.
Option B) pageContext - This option is correct because the pageContext object is available as an implicit object in JSP pages and it provides access to all the other implicit objects.
Option C) context - This option is incorrect because the context object is not available as an implicit object in JSP pages.
