The graph below shows the blackbody radiation curves for four stars. The image shows four blackbody curves, plotting the wavelength and relative brightness of stars at various temperatures. The x-axis represents the wavelength in nanometers and the y-axis represents relative brightness. There is a band of color represented as part of the graph vertically, purple, blue, light blue, green, yellow, orange and red from left to right. Curve 1 peaks at a wavelength of 600nm, Curve 2 peaks at a wavelength of ~480 nm, Curve 3 peaks at a wavelength of 500 nm and Curve 4 peaks at a wavelength of 350nm.

Which of these conclusions is correct about the curves?

When temperature increases, Curve 3 moves towards Curve 4.
When temperature increases, Curve 3 moves towards Curve 1.
When temperature decreases, Curve 2 moves towards Curve 4.
When temperature decreases, Curve 2 moves towards Curve 3.
