Option A makes the most sense since Redis supports built-in sorted sets that let you rank or sort data easily, which Memcached (Option B) doesn’t handle well. Also, ElastiCache for Redis supports encryption both in transit and at rest, which is essential for PHI. The read replica in Option C won’t really help with caching or ranking, just read scalability. DynamoDB with DAX (Option D) is good for caching but doesn’t have native sorting/ranking features like Redis, so it’s less ideal given the requirements.
