How do you install the Health Cloud package in your organization?

To install the Health Cloud package in your organization, obtaining the package URL from your contract and logging in is the correct approach. This method ensures that you are using the version of the Health Cloud package that is specifically tailored for your organization, based on the agreements and contracts you have with Salesforce. The package URL typically allows for a direct installation that ties back to your organization's unique settings and entitlements.

Option A, while a common method for obtaining apps, does not necessarily ensure you are installing the correct version linked to your organization's contractual obligations. Option C points to enabling Health Cloud within Setup, which is not the correct process for installation; instead, Health Cloud must be installed as a package. Lastly, option D’s mention of Package Manager is irrelevant because this component is not the correct step to install Health Cloud directly. Each of these alternatives lacks the specificity and direct relevance that logging in using the package URL provides, making B the correct answer.
