Which mechanism causes increased gravitational redshift of photons escaping from extremely dense neutron stars?

💡 Explanation

Gravitational redshift increases because spacetime curvature near a neutron star's intense gravitational field stretches the photon's wavelength as it loses energy escaping, therefore 'A' is correct rather than alternative scattering or accelerating expansion explanations.
