Task: Answer the multiple choice question.
Query: Which drug exhibits a -13.178\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) COc1ccc(/C=N/NC(=O)CN(CCc2ccccc2)S(=O)(=O)c2ccc(NC(C)=O)cc2)cc1OC
b) COc1ccc(S(=O)(=O)Nc2ccc3oc(C)c(C(=O)O)c3c2)cc1
c) O=C(CCCNS(=O)(=O)c1cccs1)N1CCN(c2ccc(F)cc2)CC1
Answer: c. O=C(CCCNS(=O)(=O)c1cccs1)N1CCN(c2ccc(F)cc2)CC1
