Superheated steam is characterized by which of the following?

Superheated steam is indeed characterized by having a temperature that is higher than the saturation temperature corresponding to its pressure. When water is heated above its saturation temperature, any additional heat supplied increases the temperature of the steam without changing its pressure. This characteristic makes superheated steam particularly useful in various applications, such as driving turbines efficiently, as it is less likely to cause corrosion or erosion in equipment due to reduced moisture content.

While other options may seem relevant, they primarily describe different aspects or contexts of steam rather than defining superheated steam directly. For example, although superheated steam is often dry and has low moisture content, indicating characteristics of superheated steam, it is the elevated temperature above saturation that fundamentally defines it. Thus, the key identifying feature of superheated steam is its temperature being higher than the saturation temperature.
