Answer 1

Correct option is (a) cool, warm

The best I can explain: The usual difference of temperature between inside and outside is kept as about 8°C to 10°C. With regards to human comfort, the term effective temperature is used. It is an index which combines the effect of air movements, humidity and temperature.
