Task: Answer the multiple-choice question.
Query: Which drug exhibits a -10.133\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CCOC(=O)c1c(C)[nH]c(C(=O)C(C)OC(=O)C2=COCCO2)c1C
(b) CCN(C(=O)COC(=O)c1cccc(S(=O)(=O)N2CCOCC2)c1)C1CCS(=O)(=O)C1
(c) CC(C)[C@H](NC(N)=O)C(=O)NCCc1ccc(Cl)cc1Cl
(d) O=C1OC2CC3CC1CC(O)(C3)C2
Answer: c. CC(C)[C@H](NC(N)=O)C(=O)NCCc1ccc(Cl)cc1Cl
