Statement 3 is incorrect.
  • The first detection of gravitational waves was announced on February 11, 2016. These had been predicted, almost exactly a century ago by Albert Einstein as a natural consequence of his theory of gravity — the Theory of General Relativity. General Relativity implies that under certain circumstances, space itself would be stretched and compressed resulting in the production of gravitational waves — much like throwing a stone in a placid pool of water.
  • Since gravitational waves were first detected by LIGO (Laser Interferometry Gravitational-wave Observatory), its detectors have observed dozens of short high-frequency gravitational wave bursts. These high-frequency waves are thought to be a result of collisions of black holes — about as massive as our Sun — as well as of neutron stars. Black holes and neutron stars are stellar remnants of stars which have exhausted their nuclear fuel.

Explanation:

General Relativity and Gravitational Waves:
- The Theory of General Relativity does imply that under certain circumstances, space itself can be stretched and compressed, leading to the production of gravitational waves. These waves are ripples in the fabric of spacetime caused by the acceleration of massive objects.

LIGO and Gravitational Waves:
- Gravitational waves were indeed first detected by LIGO (Laser Interferometry Gravitational-wave Observatory) in 2015. This discovery confirmed a major prediction of Einstein's General Theory of Relativity and opened a new window to observe the universe.

Neutron Stars and Gravitational Waves:
- The collision of neutron stars actually does produce gravitational waves. When these incredibly dense stars merge, they create intense gravitational waves that can be detected by instruments like LIGO.
Therefore, the correct answer is option 'B', as only the second statement is incorrect.
