The cartridge's root-levelpackage.jsonuses the'hooks'property to point to the hook registration file. In the standard SFRA cartridge structure, the hook-registration file resides under:

cartridge/scripts/hooks.json

Therefore, the correct relative path is:

{'hooks':'./cartridge/scripts/hooks.json'}

Salesforce's SFRA hook documentation confirms thatpackage.jsonuses thehookskeyword to identify the hook file and that the referenced hook file then maps extension-point names to script implementations.

Option B omits thecartridgeportion of the normal directory structure, so it points to the wrong location. Option C uses JavaScript-object syntax rather than valid JSON because thehooksproperty name is unquoted. Apackage.jsonfile must contain valid JSON.

Thehooks.jsonfile contains entries with the extension-pointnameand correspondingscriptmodule. Once the cartridge is deployed and active on the appropriate cartridge path, registered hooks can participate in storefront or platform extension points.
