Text 3 is the correct one because it accurately describes the two dancing pairs and their clothing. It mentions one pair, featuring a man in a yellow t-shirt and a woman in a black skirt, with the man raising his arm to guide his partner into a twirl. It also describes the second pair, where the man is wearing a light blue shirt and the woman is wearing shorts, which matches the image. The description also correctly mentions the spectators and the man sitting near a speaker, without adding incorrect details.

Text 1 Although similar, it lacks precision in describing the colors of the clothing of all the dancers. It also incorrectly suggests that the man sitting might be playing music, which is inaccurate based on the image, as he is only next to a speaker.

Text 2 This description contains more significant errors, such as describing a woman in a white dress, which does not match what is seen in the image. It also mentions a guitarist playing music, which is not present in the image. Furthermore, it gets the clothing colors of some dancers wrong.
