Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.300\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) CCOC(=O)Nc1ccc2c(c1)N(C(=O)OCCN(C)C)c1ccccc1CC2.Cl
b.) O=C(Nc1ccc(N2CCOCC2)c(Cl)c1)c1cc2ccccc2o1
c.) CCOc1ccc(C(=O)NC(=S)Nc2ccc(NC(=O)C(C)C)cc2)cc1[N+](=O)[O-]
d.) O=S(=O)(Nc1ccc2c(c1)OCCO2)c1cnc[nH]1
Answer: b. O=C(Nc1ccc(N2CCOCC2)c(Cl)c1)c1cc2ccccc2o1
