A Correct answer
Explanation

Equivalent evaporation is the standard parameter used to compare steam-generating capacity of different boilers. It represents the amount of water evaporated from and at 100°C that would produce the same steam output. kg/hr varies with pressure, steam pressure is an operating parameter, and thermal efficiency is a ratio, not a capacity measure.
