Solution

The correct options are
A
Cross sectional area

C
Temperature difference

The flow of heat indeed depends on temperature difference between the two bodies like it always flow when one body is at higher temperature than that of second body. And if the area also matter in transfer of heat. For example, the tea kept in a saucer gets colder at faster rate than the tea in a cup.
