Correct answer & explanation
✓
Replatform the database to Amazon RDS for an open-source engine like PostgreSQL
(Replatform the database to Amazon RDS for an open-source engine like PostgreSQL) is correct because migrating to an open-source database on Amazon RDS eliminates the need for commercial licenses, thereby reducing licensing costs. Option A (Rehost) is incorrect because it retains the same commercial database software, so licensing costs remain. Option C (Repurchase to SaaS) may not be applicable or cost-effective for the database. Option D (Refactor to DynamoDB) typically requires significant application changes and may not align with a license cost reduction goal.
