Solution
The correct option is C 2 only
The ice cream is at a temperature lower than the surroundings. This difference in temperature causes the heat flow between them. Heat absorbed by the ice cream from the surrounding causes an increase in the temperature of ice cream and thus, results in melting of ice cream.
