Which change occurs to a neutron star's intense gravity field when significant mass accretes onto it?

A)Frame dragging effect increases sharply
B)Schwarzschild radius compresses dramatically
C)Hawking radiation decreases exponentially
D)Gravitational redshift vanishes asymptotically

💡 Explanation

Accumulating mass causes spacetime curvature to increase radically, intensifying the frame dragging effect, because angular momentum of the accreting matter is incorporated into the neutron star. Therefore, frame dragging increases; rather than a Schwarzschild radius shrinking (increases); Hawking radiation diminishing, or redshift vanishing.
