Answer: The answer is (c) The temperature every morning at 8am.
Step-by-step explanation: We are given four options and we are to select which situation among them can be best modelled by a continuous relationship.
A continuous relationship can be seen in a group of data where the values belonging to the group can take any value within a finite or infinite interval.
And a discrete relationship can be seen in a group of data where the values belonging to the group are distinct and separate.
We can easily see from the options that (a), (b) and (d) will fall in discrete relationship because the values here will be distinct and separate.
But, in option (c), the values of the temperature falls in a continuous relationship.
Thus, the correct option is (c).
