Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.265\% 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: Cc1cc(C(=O)NCC(=O)Nc2c(C)cccc2C)c(C)o1
b: Cc1ccccc1OCC1CNC(=O)O1
c: O=C(COC(=O)COc1ccccc1Cc1ccccc1)Nc1cccnc1Cl
d: O=C(CSc1nnc(-c2cccnc2)n1Cc1ccco1)N1CCc2ccccc21
e: CSc1ccc(Cn2nnc(C(=O)Nc3ccc(C)c(C)c3)c2N)cc1
Answer: b. Cc1ccccc1OCC1CNC(=O)O1
