main reason "c" is correct is that all the other choices are too "wordy". Concise is the way to go!

A lack of X means NOT ENOUGH OF X.
A: a lack of some other doctor
Here, the conveyed meaning -- that there is NOT ENOUGH OF SOME OTHER DOCTOR -- is nonsensical.
Eliminate A.
.
The future tense cannot serve to express a CONDITION.
For this reason, unless + FUTURE TENSE is ALWAYS WRONG.
Generally, the verb in an unless-clause should be in the SIMPLE PRESENT TENSE.
Incorrect: John will not attend unless Mary will attend.
Correct: John will not attend unless Mary ATTENDS.

B: unless there will be another doctor
Here, will be (future) cannot serve to express the condition conveyed by the unless-clause.
Eliminate B.

E: damage lacking another doctor
Here, lacking another doctor seems to modify damage, implying that DAMAGE is LACKING ANOTHER DOCTOR.
Not the intended meaning.
Eliminate E.

A modifier should be AS CLOSE AS POSSIBLE to what it serves to modify.
C: without another doctor's testimony about proper medical procedures
D: testimony from some other doctor about proper medical procedures
C is free of errors and positions about proper medical procedures closer to its intended referent -- testimony -- than does D.
Eliminate D.

The correct answer is C.
