I have a hard time to understand this structure: about + clause. I thought a clause can not follow the word "about".
Can anyone help to elaborate this grammar? Thanks.
You're right. Here in E we don't have clauses that begin with "about":
Astronomers studying the newly discovered star
say that it provides clues about our galaxy’s origin,
that it may supply data about how fast our galaxy is expanding, and
that it is perhaps the most distant star in the entire Milky Way.
We have subject (asrtonomers), verb (say) and 3 clauses that begin wit "that".
"About" here is an object of "clues" in the first that-clause and "data" in the second that-clause.
Answer E maintains a good parallel structure.
Hope it's clear...

(A) about how fast our galaxy is expanding, and moreover it is perhaps
(B) regarding the speed our galaxy expands at; moreover, they think it may be
(C) about how fast our galaxy expands and perhaps be
(D) on the galaxy’s expansion rate and perhaps
(E) about how fast our galaxy is expanding, and that it is perhaps
