Bscreen tubes, generating tubes, and then superheater
Csuperheater, economizer, and then generating tubes

AI Explanation
The correct answer is D) economizer, superheater, generating, and then screen tubes. The proper sequence for washing the sections of a boiler is to start with the economizer, then move to the superheater, followed by the generating tubes, and finally the screen tubes. This sequence ensures that the water flow effectively cleans the boiler from the least to the most critical components. The other options are incorrect because they do not follow the proper order. For example, option A starts with the generating tubes instead of the economizer, while option B skips the economizer entirely. Option C reverses the order of the economizer and superheater.
