Task: Answer the multiple-choice question.
Question: Which drug exhibits a 17.852\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) S=C(Nc1ccc(Cl)cc1Cl)N1CCOCC1
b) Oc1ccc(Br)cc1/C=N/NC(=S)NCCc1ccccc1
c) CCC(=O)Nc1ccc(N2CCN(S(C)(=O)=O)CC2)cc1
d) O=C(NC1CC1)c1ccc2c(c1)C1C3CCC(C3)C1C(c1ccccc1)N2
Answer: c. CCC(=O)Nc1ccc(N2CCN(S(C)(=O)=O)CC2)cc1
