A) Before its bankruptcy in 2008, Goldman Sachs Inc. financed Crystal Technologies, a tech company, as a venture capital investment and they would withdraw all its funding
--> Here 'its' refers to 'Goldman Sachs Inc' so changes the meaning of the sentence. 'and they would withdrew all their funding' creates run-on sentence.

B) Before its bankruptcy in 2008, Goldman Sachs Inc. had financed Crystal Technologies, a tech company, as a venture capital investment and withdrew all its funding
--> Same error as A

C) Before its bankruptcy in 2008, Crystal Technologies, a tech company, had been financed by Goldman Sachs Inc. as a venture capital investment and the investor withdrew all its funding
--> 'and the investor withdrew all its funding XXX' creates run-on sentece

D) Before its bankruptcy in 2008, Crystal Technologies, a tech company, was financed as a venture capital investment by Goldman Sachs Inc., which withdrew all its funding
--> Here 'Before its bankruptcy in 2008' modifies Crystal technologies as this company became bankrupt. CORRECT

E) Before its bankruptcy in 2008, Crystal Technologies, a tech company, was a venture capital investment of Goldman Sachs Inc. , who withdrew all its funding
--> Here 'who' refers to 'Goldman Sachs Inc.', which is a thing and WHO can modify only people so usage of who is incorrect.

D why use of had been in option c wrong
