Answer: The answer is indeed C) I will be a spectator at the game today.
Step-by-step explanation:
The English word "spectator" has originated from the Latin word "spectare" - frequentative form of "specere" -, that means to observe, to watch, to gaze at. Thus, a spectator is a person who sees, who watches something happen. The speaker in option C will merely watch the game, he/she won't take part in it.
