Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.782\% 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: Cc1cc(OCC(=O)NCC(O)c2ccccc2)c2c(C)c(C)c(=O)oc2c1
b: CCOC(=O)C(=CNc1nc2ccc(C(=O)OCC)cc2s1)C(=O)OCC
c: CSc1sccc1/C=N/NC(=O)c1ccncc1
d: Cn1c(O)c(C=NCCN2CCN(C(=O)Nc3ccccc3)CC2)c(=O)n(C)c1=O
e: O=C(Nc1ccn(Cc2cccc3ccccc23)n1)c1cccnc1
Answer: b. CCOC(=O)C(=CNc1nc2ccc(C(=O)OCC)cc2s1)C(=O)OCC
