Task: Answer the multiple choice question.
Question: Which drug exhibits a -18.200% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) Cc1cc(OCCCCCNCCO)ccc1Cl
b) CCC(C)n1ncn(-c2ccc(N3CCN(c4ccc(OCC5COC(Cn6cncn6)(c6ccc(Cl)cc6Cl)O5)cc4)CC3)cc2)c1=O
c) CCOC(=O)N1CCN(C(=O)c2oc3ccc(S(=O)(=O)N4CCCCCC4)cc3c2C)CC1
d) CCN(CC)S(=O)(=O)c1cccc2nsnc12
