A simultaneous analysis of the Michelson-Morley and Pound-Rebka
experiments would show that (3) is the only reasonable case. That is,
the speed of light decreases (varies with the gravitational potential
V) in accordance with Einstein's 1911 equation c'=c(1+V/c^2) while the
wavelength remains constant. Equivalently, in the absence of a
gravitational field, the speed of light varies with the speed of the
light source v in accordance with the equation c'=c+v given by
Newton's emission theory of light. There is neither gravitational nor
any other time dilation.
