Solution

The correct option is A $10^{\circ} C$
Temp = $20^{\circ} C$ Dew point = $10^{\circ} C$
The place is saturated at $10^{\circ} C$
Even if the temp drop dew point remains unaffected.
The air has V.P. which is the saturation VP at $10^{\circ} C$ . It (SVP) does not change on temp.

BOOK ANSWER : 10°C

MY SUGGESTION :

My answer is also same as book because I think that dew point do not depend on environment temperature.

But I want to know that the reason I have mentioned is true or not, if my reason is wrong then why?
