Which of the following is NOT a spontaneous reaction?

a. Ice melting at 25 °C under atmospheric pressure
b. Water freezing at 25 °C under atmospheric pressure
c. Two gases mixing in the same container
d. A gas expanding into a larger volume container
e. A hot object warming up a colder object in contact with it

My answer was e but it is wrong, so I'm now thinking it would be b but it says under atmospheric pressure which leads me to think it's spontaneous. I'm so confused can someone help. Thanks
