Explanation

High IO cloud hard disks are the cheapest among the four options listed, making them the most suitable choice for a development and testing environment where cost efficiency matters more than peak performance. Ultra-high IO disks (option A) offer significantly higher IOPS and throughput than High IO but at a greater cost, which is unnecessary for non-production workloads. Extremely fast SSD disks (option C) sit at the top of the performance and price tier, designed for latency-sensitive production workloads like large databases, making them overkill and expensive for dev/test use. Universal SSD disks (option D) provide a balance of performance and cost suited for general production use, but they are still priced higher than High IO disks.

Memory tip: Rank the disk types from cheapest to most expensive as High IO, Universal SSD, Ultra-high IO, Extremely fast SSD. For exam questions pairing "development/testing" with "cheapest," always pick High IO, since dev/test environments prioritize cost savings over raw performance.
