(C) Time taken to complete a task
(D) Weight of a person​

Answer 1

Explanation:

A) Temperature of water

Answer 2

(B) Number of persons in a family is not a continuous variable.

A continuous variable is a variable that can take infinitely many values. The different values can be continuous and can be any real number. For a continuous variable, all the real numbers are the possible values.

Here among the given options the temperature of the water, the time taken to complete a task, and the weight of a person are some examples of continuous variables as all the real numbers can be the value of these variables.

While the number of members in a family is not a continuous variable as it can take only whole numbers as its values and decimal values cannot be taken by this variable.
