Which mechanism causes an observed gravitational redshift of spectral lines emitted by hot, extremely dense white dwarf stars?

A)Gravitational time dilation
B)Increased convective cooling
C)Nuclear fusion fluctuations
D)Relativistic beaming effect

💡 Explanation

Gravitational redshift occurs when light emitted from a strong gravitational field loses energy via gravitational time dilation. Because equivalence dictates gravity warps spacetime around the star, therefore the redshift increases, rather than other mechanisms influencing emitted wavelength.
