The correct answer is "Merah, jingga, kuning, hijau, biru, ungu". This is because when white light passes through a prism, it gets refracted and separates into its component colors, forming a spectrum. The colors in the spectrum are arranged in the order of their wavelengths, with red having the longest wavelength and violet having the shortest. The correct answer lists the colors in the correct order, starting with red and ending with violet, which matches the phenomenon of light dispersion through a prism.
