Sentence Correction: Relative Clauses - Choosing the Correct Relative Pronoun

The Oklahoma City Police Department is questioning two suspects who their fingerprints were found at the scene of the crime.

There is a possessive relationship between the suspects and the fingerprints: the fingerprints belong to the suspects. There is a certain relative pronoun - not who - that should be used when such a relationship exists.      

What helps us identify this question as a Relative Clause question as well as identify the mistake is the following Stop Sign:

who, which, that, whose, whom

This answer choice repeats the original Relative Clause error. There is a possessive relationship between the suspects and the fingerprints: the fingerprints belong to the suspects. There is a certain relative pronoun - not whom - that should be used when such a relationship exists.

What helps us identify this question as a Relative Clause question as well as identify the mistake is the following Stop Sign:

who, which, that, whose, whom

While this answer choice corrects the original Relative Clause mistake by using the correct relative pronoun in the case of a possessive relationship, it is stylistically flawed. Using the passive form (are being questioned) creates Redundancy. Since there is another grammatically correct answer choice that does not use the passive form, it is preferable to this one.

That's the way!

There is a possessive relationship between the suspects and the fingerprints: the fingerprints belong to the suspects. This answer choice corrects the original Relative Clause mistake by using the correct relative pronoun (whose) in the case of a possessive relationship.
