Which of the following correctly describes how light will be affected as it tries to escape from a massive object?
A) Light escaping from a compact massive object, such as a neutron star, will be redshifted.
B) Visible light escaping from a compact massive object, such as a neutron star, will be redshifted, but higher frequencies, such as X-rays and gamma rays, will not be affected.
C) Less energetic light will not be able to escape from a compact massive object, such as a neutron star, but more energetic light will be able to.
D) Light escaping from a compact massive object, such as a neutron star, will be blueshifted.
E) Light doesn't have mass; therefore, it is not affected by gravity.
