I narrowed it down to B and C as these two try to qualify "many “Roswellians” ".
C-> the construction "many “Roswellians” are convinced " does not goes with "Basing it".
B-> "Swayed by..." correctly qualifies "many “Roswellians” . Hence Correct.

IMO B as explained by ravi.
The "it" in C has no referrent.
A implies that many Rosellians are based on eye-witness accounts.
In D, the usage of "with" is incorrect because the two clauses are not reinforcing into each other. The usage of "with" should have been like:
With two children at home, Rachel has no time for her hobbies.
E implies that many Rosellians are convinced by many eye-witness accounts.

+1B
Hope that helps.

In A, there is modifier issue.
It implies that many Rosellians are based on the fact.
Hope that helps.

Hi Marcab,

could you explain D a little bit more? I do not understand why "with" could not be used here.

Thanks

Hi lucky1829,
the question checks us on the use of modifier....
as in non underlined portion, the modifier is "many “Roswellians”", the dependent clause cannot start with "based on"... so A out .. as you are asking about D lets look at the correct answer and D..

B)Swayed by eye-witness accounts, claims of alien autopsy footage, and local folklore
many “Roswellians” are swayed by.. so correct usage...

D)With eye-witness accounts, claims of alien autopsy footage, and local folklore used for a basis...
firstly the usage of "with" is not correct here... with... is an adverbial modifier..
here if i take the modifier , the first part to be correct..... then it should be modifying some facts,books account ie the recipient and not the subject ....
correct eg... using eye-witness accounts, claims of alien autopsy footage, and local folklore as a basis, many....

another way is just place the two parts next to modifier and see if it makes sense

1)B)Swayed by eye-witness accounts, claims of alien autopsy footage, and local folklore..
many “Roswellians”,Swayed by eye-witness accounts, claims of alien autopsy footage, and local folklore, are convinced that some type of extra-terrestrial crash-landing occurred in the New Mexico desert in 1947.... sounds correct..

2)D)With eye-witness accounts, claims of alien autopsy footage, and local folklore used for a basis...
many “Roswellians”,With eye-witness accounts, claims of alien autopsy footage, and local folklore used for a basis, are convinced that some type of extra-terrestrial crash-landing occurred in the New Mexico desert in 1947.... does not fit in properly

That is because “Roswellians” are not "with" eye-witness accounts, claims of alien autopsy footage, and local folklore! "With" is used in the sense of "together with" (for example, you get 1 item free "with" one item that you buy).

However, I find it slightly surprising that B uses "swayed", which is not used in the original sentence at all.

hi SG,
the sentence ,when fitted with choice A would read....

Based on eye-witness accounts, claims of alien autopsy footage, and local folklore, many “Roswellians” are convinced that some type of extra-terrestrial crash-landing occurred in the New Mexico desert in 1947.

we have to look at choices satisfying the nonunderlined portion. in the non underlined portion the modified noun is "many “Roswellians”", so we look at the modifying clause...
it is..Based on eye-witness accounts..... if we put these two things together the question we can ask is.. Can some person be based on eye witness accounts.... no... based on eye.... has to modify some work, book, documentary etc
Since it will be some book, work,fact etc which can be based on eye witness accounts
