Task: Answer the multiple-choice question.
Question: Which drug has a 16.787\% 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, or d without using any other words.
Options:
[a] O=C(N/N=C/c1ccc(N2CCOCC2)cc1)c1ccccc1OCCOc1ccccc1
[b] Cc1ccc(NC(=O)CS(=O)(=O)c2cn(C)c3ccccc23)c(C)c1
[c] O=C(CSc1nc2ccc(Nc3nc(N4CCOCC4)nc(N4CCOCC4)n3)cc2s1)Nc1ccccc1Cl
[d] Cc1ccccc1-c1nnc(CN2CCC(C)CC2)o1.Cl
