Q.  
When the pressure at which heat is added in Rankine cycle increases, the moisture content at the turbine exhaust


Answer & Explanation

In the Rankine cycle, which is used in steam power plants, increasing the pressure at which heat is added raises the temperature of the steam. This results in more moisture remaining in the steam as it expands and exits the turbine. The moisture content at the turbine exhaust increases because the steam doesn't fully evaporate, leading to a less efficient turbine performance. This effect is important when designing power systems for maximum efficiency and minimizing wear and tear on turbine components.

Thus correct option is: A.
