While they protect employees from financial ruin, give customers peace

(A) purchase it, and, as an increasingly well-publicized perk, that make
--> the 'that' distorts the parallelism:
'...provide cost certainty for companies that purchase it, and, as an increasingly well-publicized perk, that make it easier for firms to recruit top personnel.
Looks like we have two different companies: the ones that buy the policy and the ones that make recruitment easier. But making recruitment easier just is another perk of the policy.

(B) purchase it, and an increasingly well-publicized perk, are makers of
--> the part after the last comma makes no sense if you complete the sentence.
"...purchase it, and an increasingly well-publicized perk, are makers of it easier for firms to recruit top personnel."

(C) purchase it and, as an increasingly well-publicized perk that are making
--> S-V error: perk is singular, therefore 'are' is incorrect
Furthermore, the first part of the sentence is incomplete since nothing follows the 'and' before the comma. There is no comma in or after the underlined portion that would make it a modifier.

(D) purchase it and an increasingly well-publicized perk, for making
--> that changes the meaning. It seems like they are purchasing both: 'it' (the policy) and 'an increasingly well-publicized perk' (but what perk?).

(E) purchase it and, as an increasingly well-publicized perk, make
--> this puts both perks of the policy in a nice, parallel way
"...corporate liability insurance policies also provide cost certainty for companies that purchase it and, as an increasingly well-publicized perk, make it easier for firms to recruit top personnel."

Answer E

Hi Bunuel,
I am confused about the use of "it" in this question
"While they protect employees from financial ruin, give customers peace of mind, and encourage safety, corporate liability insurance policies also provide cost certainty for companies that [u]purchase it"


how can it be used for corporate liability insurance policies??

In the non - underlined part "they" refers to "policies", then how in correct answer choice "it" refers to "policies". This looks incorrect. A, C, & D have no working verb. B has S-V agreement error.
