Northern Trail Outfitters (NTO) wants email subscribers to adopt their app.

Comprehensive and Detailed Explanation:

Correct answers are A, C, and D.

A — Long and Short Codes are country-specific; availability must be checked per country.

C — Inbound messaging (users texting keywords to subscribe) generally requires local Short or Long Codes.

D — MobileConnect is not supported in every country; Salesforce provides a list of supported regions.

❌ Why others are wrong:

B: Customers are billed by Salesforce, not directly by the mobile carriers.

E: Opt-ins can occur via Web Forms, Mobile Keyword responses, or API — not only via inbound messaging.
