Boiler rating is the heating capacity of a steam boiler. It is expressed in BTU per hour (BTU/h), horsepower (hp), or steam output in kg/hr at 100°C’ and atmospheric pressure. Each kilogram of steam receives 2257 kJ of heat from the boiler.
The rating indicates the maximum capacity of a boiler. When a boiler operates at its maximum rated capacity, it is referred to as the maximum load. If the load varies from hour to hour, it operates at a varying load. Load and load variations can influence the amount of chemicals required for treatment and the treatment controls required.

Main function of boiler is to generate steam for generating power by rotating turbine blades. So, if you increase the mass flow rate of steam then, you can easily raise power output. And, boiler rating is depends upon power output. So, D is correct option.
