Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.897\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCOc1ccc(/C(CCC(=O)O)=N/NC(=S)NCCc2ccccc2)cc1
b: O=C(CSc1nc(C2CC2)nc2ccccc12)Nc1ccccc1N1CCOCC1
c: Cc1c(CCC(=O)NCCCn2ccnc2)c(=O)oc2cc3occ(C(C)(C)C)c3cc12
d: CCS(=O)(=O)Nc1cccc(C2=NN(S(=O)(=O)c3ccc(F)cc3)C(c3cccs3)C2)c1
e: CC1(C)CC(=O)C=C(NC2CCCCC2)C1
Answer: b. O=C(CSc1nc(C2CC2)nc2ccccc12)Nc1ccccc1N1CCOCC1
