Refer to the Exhibit. What will be the result of selecting the highlighted device?

When the highlighted device is the same device already in use by the datastore, selecting it initiates an expand operation that consumes the remaining unallocated space on that device, growing the datastore up to 200.01GB total. This is distinct from adding an extent, which requires a separate device not yet associated with the datastore. The operation increases the single extent's capacity using the device's available free space without creating a new extent.

Adding a second extent requires selecting a different device not already used by the datastore; selecting the existing device's remaining free space expands the current extent instead of creating a new one.

The physical device capacity is fixed at 200.01GB and cannot be increased beyond that limit through this operation; the datastore grows up to the available free space, not beyond the device's hardware boundary.

The device is valid for expansion because it has available free space on the same device already used by the datastore, making it fully suitable for the grow operation.
