Dry bulb temperature increases.
Specific Humidity decreases.
Dew point temp decreases.
Relative humidity decreases.
Enthalpy and wet bulb temp remain constant.
So, Sp. Volume increases.
Specific Humidity decreases.
Dew point temp decreases.
Relative humidity decreases.
Enthalpy and wet bulb temp remain constant.
So, Sp. Volume increases.

WBT CONSTANT.
DBT INCREASES.
DPT DECREASES.
DBT INCREASES.
DPT DECREASES.

In dehumidification, point rolls toward downward in the psychrometric chart.
So I think that DPT AND WBT decreases but DBT remains constant.

They asked in chemical dehumidification process. Then what about the answer?

D. Is correct because chemical dehumidification process is a inclined downward line with increasing DBT.
Shibunath said:

Chemical dehumidification takes place along constant enthalpy line i.e WBT line. Hence, WBT remains constant while DBT, DPT and specific humidity decrease.

In chemical dehumidification process WBT will remain constant.

Option D is correct.
By tracing the line of de-humidification on Psychometric chart. It is clear that;
1) Wet Bulb Temperature DECREASES.
2) DEW Point Temperature DECREASES.
As for dehumidification, some amount of vapours condenses, giving out energy in the heat which raises the sensible temperature!
So, Option D is correct
