Explanation:

The correct selections are Information Protection and Data Loss Prevention . Microsoft documents that Microsoft Purview Information Protection helps organizations discover, classify, protect, and govern sensitive information wherever it lives or travels . Microsoft also describes Information Protection as the Purview solution for data classification, sensitivity labels, and encryption , including scenarios across Microsoft 365, on-premises repositories, cloud stores, and even third-party apps through supported extensions. That makes it the correct choice for the requirement to discover and classify sensitive data across multiple platforms .
For the second requirement, Microsoft states that Microsoft Purview Data Loss Prevention (DLP) helps prevent the unintentional sharing of sensitive items and can block users from prohibited activities , including inappropriate external sharing through services such as SharePoint, OneDrive, Teams, and email.
Microsoft specifically documents DLP scenarios for preventing sensitive items from being shared with external users , which matches the requirement to block users from sharing intellectual property externally.
