Which of the following are physical parameters to decide the water quality?
A. pH
B. Temperature
C. Total Suspended Solids (TSSs)
D. Hardness
E. Conductivity
Choose the correct answer from the options given below:

Correct option is D

There are three main water quality parameters to measure the quality of water: Physical, chemical and biological. Physical water quality parameters include eight principle indicators: electrical conductivity, salinity, total suspended solids (TSSs), turbidity, temperature, color, and taste and odor.
Hence, option (d) is correct.
