Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.991\% 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 additional words.
Options:
a: O=C(Cn1cnc2ccccc2c1=O)NCCC(=O)Nc1ccc2c(c1)OCCO2
b: CC(=O)Nc1c(C)cc(S(C)(=O)=O)cc1C
c: COc1cccc(-c2nc(CS(=O)(=O)CC(=O)NCc3ccc4c(c3)OCO4)c(C)o2)c1
d: CCOC(=O)c1c(C)n2c3c(cc(C)cc13)CCC2
e: COc1cccc2c1Oc1cc([N+](=O)[O-])cc(N(C)C(C)=O)c1C=C2
Answer: d. CCOC(=O)c1c(C)n2c3c(cc(C)cc13)CCC2
