Comprehensive Explanation

Editable templates in Adobe Experience Manager separate template configuration into Structure, Initial Content, Content Policies, and Layout.

The Structure section defines components that must remain consistent across pages created from the template. Components placed in this section can be locked to prevent page authors from modifying, moving, or deleting them.

When a component is locked in the template structure, it remains visible on resulting pages but cannot be edited directly by ordinary page authors.

This capability is particularly useful for mandatory page elements such as standardized headers, regulatory notices, branding elements, and structural containers.

Option A is incorrect because removing a component from the allowed-components policy restricts its availability for insertion; it does not establish an existing, non-editable component.

Option B is incorrect because Initial Content provides starting content that authors can subsequently modify on individual pages.

Option C does not provide the required template-level editing restriction.

The appropriate implementation is therefore to place the component in the editable template's Structure section and maintain it in a locked state.

Adobe's editable-template documentation explicitly distinguishes locked structure components from editable initial content, establishing the correct behavior for this requirement.
