Question

the term \conductivity\ refers to: choose an option below electrical resistance the measurement of the concentration of dissolved solids in the water the type of metal used in cooling tower construction proper grounding of water chillers

Explanation:

Conductivity in water testing measures how well water conducts an electric current, which directly relates to the concentration of dissolved ionic solids (salts, minerals) in the water. The other options are incorrect: electrical resistance is the opposite of conductivity, cooling tower metal type and chiller grounding are unrelated to the definition of conductivity.

Answer:

B. the measurement of the concentration of dissolved solids in the water
