Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.856\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CC(C)N1C(=O)CC2(CC[N+](C)(CCOC(=O)C(c3ccccc3)c3ccccc3)CC2)C1=O.[I-]
b COc1ccc(C2=C(SC)CC2=NC(C)(C)C)cc1
c O=C(O)c1cccc(NC(CNS(=O)(=O)c2ccc(Cl)cc2)c2ccccc2)c1
d Cc1cccc(NC(=O)COc2nsnc2N2CCOCC2)c1
Answer: c. O=C(O)c1cccc(NC(CNS(=O)(=O)c2ccc(Cl)cc2)c2ccccc2)c1
