Final Answer :
A
Explanation :
Technician A is correct because hygroscopic brake fluid does absorb moisture from the air, which is a characteristic of brake fluids like DOT 3, DOT 4, and DOT 5.1. Technician B is incorrect because DOT 4 brake fluid actually has a higher boiling point than DOT 3 fluid, not the other way around.
