Salesforce's official Grants Management installation prerequisites directly support B, C, and E . Grants Management requires the appropriate Grants Management licensing together with Customer Community Plus Login licenses for the external grantseeker experience. Salesforce also requires Lightning Experience and Chatter to be enabled.

Therefore, because the agency's employees currently operate in Salesforce Classic, they must move to Lightning Experience to use the supported Grants Management experience. Chatter must also be enabled because the package depends on Salesforce collaboration functionality. For the external grant portal, Customer Community Plus provides the supported external-user licensing required by the managed-package implementation.

The distinction between options B and D is significant. Although Customer Community is appropriate for many high-volume constituent portals, the Grants Management managed-package prerequisites specifically identify Customer Community Plus Login licensing. This is therefore a product-specific requirement, not merely a generic Experience Cloud licensing choice.

Web-to-Lead concerns conversion of public web submissions into Lead records and has no role in installing or enabling Grants Management.

Salesforce additionally lists Digital Experiences and My Domain among the overall prerequisites, although those choices are not provided in this question.
