CSidebar ID must be uppercase

Solution:

Step 1: Understand correct hook for sidebar registration
Sidebars must be registered on 'widgets_init' hook, not 'init'.

Registering on 'init' is too early or wrong timing, so dynamic_sidebar() finds no registered sidebar.
Final Answer:
Sidebar registered too late; should use 'widgets_init' hook -> Option D

Use 'widgets_init' to register sidebars [OK]

Quick Trick: Register sidebars on 'widgets_init' hook [OK]
