Which consequence results on a binary pulsars orbital period due to gravitational radiation?

A)Orbital decay rate increases
B)Periastron precession reverses steadily
C)Emitted frequency exhibits blueshift
D)Mass transfer becomes highly unstable

💡 Explanation

The orbital period decreases because gravitational radiation causes orbital decay through energy loss, explained via mass-energy equivalence causing this energy loss during orbital motion; therefore, the decay rate accelerates, rather than other orbital elements changing significantly at this stage.
