IMO B
Unlike should be used and thus D,E rejected.
c) where is used to refer to a place not businesses
a)position of 'which' is incorrect and also in b)the failure rate maintains parallelism

Unlike mainstream American businesses, more than half of which fail[/i], the failure rate for
businesses in the Amish community hovers around 5 percent.

A. Unlike mainstream American businesses, more than half of which fail - When you start a sentence with comparison words such as like, unlike etc the subject of the following Independent clause in comparison.SO in this sentence "mainstream American businesses" is being compared to "the failure rate" which is subject of the following independent clause.This comparison is an illogical comparison.

B. Unlike mainstream American businesses, in which the failure rate is more than half
C. Unlike mainstream American businesses, where more than half of them fail

B and C also have a same problem as A has.

D. While the rate of mainstream American businesses failing is more than half-- should have been "rate of failure" not "rate of mainstream"

E. While more than half of mainstream American businesses fail-- Correct

Hi,
For those who haven't checked the link I posted, I will summarize it
In A,B,C we are comparing mainstream businesses with failure rate . So, Incorrect.
This is a tricky one. On first look D seems to be correct.
But, D has 2 issues
1) comparison would be apt if it were businesses' failing(because rate of falling should be compared as explained by GMATToppers)
2) failure rate can be 50% but not half. It is unidiomatic.

Hence, E
Cheers!
