A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.
(A) A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.
(B) After passing through a red giant stage, depending on its mass, a star will compress itself into a white dwarf, a neutron star, or a black hole.
(C) After passing through a red giant stage, a star’s mass will determine if it compresses itself into a white dwarf, a neutron star, or a black hole.
(D) Mass determines whether a star, after passing through the red giant stage, will compress itself into a white dwarf, a neutron star, or a black hole.
(E) The mass of a star, after passing through the red giant stage, will determine whether it compresses itself into a white dwarf, a neutron star, or a black hole.


OA is D....IMO - B ...(B) .After passing through a red giant stage, depending on its mass, Do "its" here refer to red giant stage rather than star

i see a problem in D

D say : Mass determines....bla bla

it does not specify mass of what ?

What's the source ?

In B, the refferant of "its" logically is "star", which is the subject of the clause

there is no problem of "its" in B

Mass of a star. To me that's implicit; I can't give u a logical answer for it.

What's the source ?

In B, the refferant of "its" logically is "star", which is the subject of the clause

'Its' not referring to star rather it's referring to 'red giant stage' because 'red giant stage' is the noun before 'its'.


IMO D because it's the most concise option, which uses 'mass' as the subject.
