Final answer:
A grass tennis court in Grand Rapids would likely use Creeping bentgrass due to its suitability for creating a fine-textured, uniform playing surface that tennis requires. The correct option is c.
Step-by-step explanation:
If you hear that an estate in Grand Rapids has a grass tennis court, you can safely assume that it is likely to be Creeping bentgrass (c). This assumption is based on the suitability of Creeping bentgrass for the fine-textured, uniform, and dense turf that is required for tennis courts. Bermudagrass could be a close option for warmer climates, but it is not as commonly used for tennis courts in regions with cooler climates like Grand Rapids. On the other hand, Kentucky bluegrass and Tall fescue are generally used for lawns and recreational sports fields due to their coarser texture and slower recovery rate when damaged.
