Task: Answer the multiple choice question.
Question: Which drug exhibits a -8.274\% 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. CCc1c(C)nc(SCC(=O)NNC(=O)c2ccco2)[nH]c1=O
b. COc1ccc(NC(=O)CCC(=O)OCc2ccc([N+](=O)[O-])cc2)cc1
c. COc1ccccc1-c1cc(C(=O)N/N=C/c2sccc2C)c2ccccc2n1
d. Cl.NCC(CC(=O)O)c1ccc(Cl)cc1
e. CCOC(=O)c1ccc(-c2ccc(/C=N/NC(=O)CN(c3cccc(C)c3)S(C)(=O)=O)o2)cc1
Answer: a. CCc1c(C)nc(SCC(=O)NNC(=O)c2ccco2)[nH]c1=O
