Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.445\% 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: COc1cccc(CNC(=O)Cn2c(=O)n(CCC(=O)N3CCCCC3)c(=O)c3sccc32)c1
b: O=C(c1nnc(-c2ccccc2)o1)C1CC1
c: COc1ccc(-c2noc(N3CCC(C(=O)Nc4cc(OC)ccc4OC)CC3)n2)cc1
d: Cc1cc(C)c2c(N)c(C(=O)Nc3nccs3)sc2n1
e: COc1ccc(OC)c(S(=O)(=O)Nc2cc3c(cc2N2CCCC2)n(C)c(=O)c(=O)n3C)c1
Answer: b. O=C(c1nnc(-c2ccccc2)o1)C1CC1
