Which risk increases when gravitational redshift measurements near a black hole event horizon do not account for spacetime curvature?

A)Underestimated tidal forces
B)Overestimated gravitational field strength
C)Inaccurate black hole mass calculation
D)Reduced Hawking radiation detection

💡 Explanation

Inaccurate SMBH mass calculation from stellar orbits follows because spacetime warps due to gravity affecting how redshift translates to orbital velocity, via general relativity, therefore calculated black hole is wrong rather than the estimation being correct if assuming Newtonian mechanics.
