India does experience the world’s largest absolute burden of several major NTDs, however, India has already

statement 3 is also correct.

Correct Answer: A
Explanation
(a) 1 and 2 are incorrect and only 3 is correct.
The visible universe like planets, stars, galaxies make up only 5% of the universe rest are Dark
matter and Dark Energy. Dark matter is 27% of the universe, 68% is Dark Energy. Thus statement
1 is incorrect.
Dark Energy appears to be associated with the vacuum in space. It is distributed evenly
throughout the universe, not only in space but also in time – in other words, its effect is not
diluted as the universe expands. Therefore statement 3 is correct.
Black holes result from massive neutron stars and not due to split in neutron stars. Statement 2 is
incorrect.
Dark energy is distributed evenly throughout the universe, not only in space but also in time – in
other words, its effect is not diluted as the universe expands. Thus statement 3 is correct.
How Do Black Holes Form?
Primordial black holes are thought to have formed in the early universe, soon after the big bang.
Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also
causes a supernova, or an exploding star, that blasts part of the star into space.
Scientists think supermassive black holes formed at the same time as the galaxy they are in. The
size of the supermassive black hole is related to the size and mass of the galaxy it is in.
