Final answer:
The number of field goals kicked in a football game is a discrete random variable.
Step-by-step explanation:
The given random variable, which is the number of field goals kicked in a football game, is a discrete random variable. Discrete random variables have countable values and are obtained by counting.
The number of field goals kicked in a football game can only take on certain values, such as 0, 1, 2, 3, and so on. It is not possible to have a fraction or a continuous range of values for the number of field goals kicked in a game.
Therefore, the answer is a. Discrete.
