In the question for words are given in each question, out of which only one word is correctly spelt. Find the correctly spelt

One simple physical concept lies behind the formation of stars: Gravitational instability. The concept is not new. Newton first perceived it late in 17th century.
Imagine a Uniform, static cloud of gas in space. Imagine then that the gas is somehow disturbed so that one small spherical region becomes a little denser than the gas around it so that the small regions gravitation field becomes slightly stronger. It now attracts more matter to it and its gravity increases further, causing it begin contract. As it contract, its density increases, which increases its gravity even more soit picks up even matter and contracts even further. The process continues until the small region of gas finally forms gravitationally bound object
The author provides information that answers which of the following questions?
(A) What causes the disturbances that changes the cloud from its original static condition?
(B) How does this small region’s increasing density affect its gravitational field?
(C) What is the end result of the gradually increasing concentration of small region of gas?
With which of the following words can you replace the word Uniform as given in this passage:
It can be inferred from this passage that the author views the information contained within it as:
