Problem statement: Answer the multiple choice question.
Query: Which drug has a 6.394\% 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 other words.
Options:
a. O=C(NCCOc1ccccc1F)C1CC(=O)N(c2ccc3c(c2)OCCO3)C1
b. O=C(NCCC1=CCCCC1)c1ccc2c(=O)n3c(nc2c1)CCCCC3
c. S=C(NCc1ccco1)Nc1cccc(Cl)c1Cl
d. COc1ccc(Cn2nnnc2C(c2cc3ccc(OC)cc3[nH]c2=O)N2CCC(C)CC2)cc1
e. CCOC(=O)c1nc(NNC(=O)c2ccc([N+](=O)[O-])cc2)sc1C
Answer: a. O=C(NCCOc1ccccc1F)C1CC(=O)N(c2ccc3c(c2)OCCO3)C1
