Which consequence results in a gravitational lens when photons pass through curved spacetime near a dense astronomical object?

A)Increased observed angular size
B)Decreased photon energy density
C)Uniform redshift of all light
D)Increased observed blue-shifted spectra

💡 Explanation

Gravitational lensing magnifies the apparent size due to spacetime curvature channeling light around the object; because spacetime is warped due to mass, photons change course through geodesics, therefore objects seem larger, rather than changed energy or uniform shifts.
