Correct: The energy increases.
Explanation: Going from red to violet the frequency increases and the wavelength decreases (E = hf, and c = λf so in vacuum the speed c stays the same). "Speed decreases" and "wavelength increases" are incorrect (wavelength decreases; speed is constant in vacuum — in materials dispersion can change speed slightly).
