Explanation:
To ensure 99.999% availability and minimize read latency for users across the globe, the company should opt for a multi-regional Cloud Spanner instance that spans multiple continents and ensure it has enough nodes to handle the replication and availability requirements. The 'nam-asia-eur1' configuration (Option A) is ideal as it covers North America, Asia, and Europe, providing global coverage and reducing latency for users in these regions. Additionally, a minimum of 3 Spanner nodes (Option C) is necessary to meet the high availability and replication needs of a multi-regional setup. Options B, D, E, and F do not fully meet the requirements for global coverage, high availability, or are not the most efficient solutions for the stated goals.
