C. No, the speaker will not fit because the diameter of the speaker is 4 inches.
To determine if the speaker will fit in the pocket, we need to compare the diameter of the speaker to the diameter of the pocket. The diameter of the speaker is given as 2 inches, while the diameter of the pocket is 2.2 inches. Since the diameter of the speaker is smaller than the diameter of the pocket, the speaker will not fit snugly in the pocket. In this case, it is better to choose a speaker with a smaller diameter that will fit comfortably in the pocket.
