It’s C because 40 to 60 percent strikes the best balance between minimizing static and preventing moisture damage. The other ranges either risk being too dry or too humid for data center equipment.

Sam X: Not A, C is better since 20-40% feels too dry for electronics in a data center.

A/B? Both seem too wide or too high; 20-40% (A) sounds too dry, and 50-75% (B) seems way too humid for sensitive gear. The ideal should avoid extremes to keep equipment stable.

C/D? I’m thinking C might be better since 40-60% is often cited to reduce static and corrosion risks realistically. D’s range feels a bit narrow and might not cover all optimal conditions.

C/D? I remember reading that the 40 to 60 percent range helps balance preventing static electricity and avoiding moisture-related corrosion. But D’s 30 to 50 percent could also be right since it leans a bit lower to reduce mold risks. A and B seem off because too low or too high humidity definitely messes with the equipment performance. So it’s between those two middle ranges for me.

Option D, because low or high extremes cause static or corrosion, so mid-range is best.

It’s D. ASHRAE recommends keeping humidity between 30 to 50 percent for data centers to avoid static electricity and corrosion issues. Option A is too low and can cause static buildup, which damages equipment. B and C have ranges that are usually higher than ideal, risking condensation problems. So, D makes the most sense here.
