An engineer is conducting a Layer 2 site survey. Which type of client must the engineer match to the survey?

Using the best client available produces overly optimistic survey results that do not reflect the real-world experience of weaker devices in the environment.

A phone client is a specific device type that may or may not be the worst performer; it is only appropriate if confirmed to be the least capable device in the deployment.

A normal client represents an average device and does not account for the performance limitations of the weakest endpoints, leading to a design that fails those devices.

Surveying with the worst client available ensures that the resulting design satisfies the needs of the least capable device on the network. If signal quality meets the threshold for the weakest client, all higher-capability clients are automatically supported. Designing to a more capable device would leave lower-end clients with insufficient coverage.
