A developer needs to create a new component called "Component A". Component A must show a list of other components that all have a resource type of existing "Component B". Component A must render this list of tiles for each Component B where the tile rendering is different from the default one. The list of rendered tiles must be reusable by future new components.
How should the developer implement this functionality?

• A.Create a script for tile rendering in Component B and use data-sly-resource attribute with a Sling selector in Component A to render the tile.
• B.Component A inherits from Component B and overwrites the base renderer to facilitate the tiles.
• C.Component A overlays Component B and overwrites the base renderer to facilitate the tiles.
• D.Component A calls the HTL of Component B directly using a data-sly-include attribute.
