Task: Answer the multiple choice question.
Query: Which drug has a -2.698% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(C1CCC(=O)N1Cc1cccnc1)N1CCN(c2ccc(F)cc2)CC1
b: O=C(COC(=O)CNC(=O)c1ccc(Cl)c([N+](=O)[O-])c1)NNC(=O)c1cccs1
c: Br.C1=C(c2cccc3ccccc23)N2CCN=C2S1
Answer: a. O=C(C1CCC(=O)N1Cc1cccnc1)N1CCN(c2ccc(F)cc2)CC1
