• B. 1, 2 and 3 only
• C. 2, 3 and 4 only
• D. 1, 3 and 4 only

Answer 1

The correct option is A 1, 2, 3 and 4

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Gravitational waves are 'ripples' in space-time caused by some of the most violent and energetic processes in the Universe.The strongest gravitational waves are produced by cataclysmic events such as colliding black holes, supernovae, colliding neutron stars and also emitted by two neutron stars as they orbit each other and then coalesce.Some gravitational waves are possibly the remnants of gravitational radiation created by the Big Bang during the formation of the Universe.
