Could anybody please tell me why there is "that" between "and" and "the mass of" in correct answer?

(A) exist at the core of nearly all galaxies and the mass of each black hole is proportional to -> missing "that" and unparallel comparison
(B) exist at the core of nearly all galaxies and that the mass of each black hole is proportional to that of
(C) exist at the core of nearly all galaxies, and that the mass of each black hole is proportional to ->false comparison
(D) exists at the core of nearly all galaxies, and that the mass of each black hole is proportional to that of
(E) exists at the core of nearly all galaxies and the mass of each black hole is proportional to that of

kimhoon27 The repetition of a structuring word such as "that" often helps us to see the intended meaning and structure. Scientists have found evidence of two things: THAT black holes exist and THAT the mass is proportional.

Scientists have recently found evidence that black holes—regions of space in which matter is so concentrated and the pull of gravity so powerful that nothing, not even light, can emerge from them—probably exist at the core of nearly all galaxies and the mass of each black hole is proportional to its host galaxy.

(A) exist at the core of nearly all galaxies and the mass of each black hole is proportional to
(B) exist at the core of nearly all galaxies and that the mass of each black hole is proportional to that of
(C) exist at the core of nearly all galaxies, and that the mass of each black hole is proportional to
(D) exists at the core of nearly all galaxies, and that the mass of each black hole is proportional to that of
(E) exists at the core of nearly all galaxies and the mass of each black hole is proportional to that of

Press Kudos if you like the post

A,C is out.. we have incorrect comparison between Mass of galaxy to host galaxy
Also A,C has parallelsim error..DC(that black hole..to IC(following and)

D,E is out SVA error.
Black holes doesnt go with exist

So we are left with B now..which is concide,direct and clear and the best choice.

+1 for option B. Use S-V and parallelism. B vs C ; C uses ", + and" - causing structure issues ! The logical meaning demands that we use a list using that and that parallelism. Hence option B.
