Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 9.866\% human ether-à-go-go related gene (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 COc1ccc(C(=O)NC(=S)Nc2ccc(S(=O)(=O)Nc3cc(OC)nc(OC)n3)cc2)cc1
b CCCc1c(C)nn(-c2ncccc2[N+](=O)[O-])c1C
c CC(NC(=O)Cc1ccsc1)c1ccc(Cl)cc1Cl
d O=C(Nc1nc2ccccc2s1)c1cccc(N2C(=O)CCC2=O)c1
Answer: d. O=C(Nc1nc2ccccc2s1)c1cccc(N2C(=O)CCC2=O)c1
