Task: Answer the multiple choice question.
Query: Which drug has a 14.447\% 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: O=C1/C(=C/c2ccc(O)cc2)SC(=S)N1Cc1cccnc1
b: CCOC(=O)CSC1=C(C#N)C(c2ccc(C)cc2)C(C(=O)OC)C(=O)N1
c: Cc1ccc(-c2noc(COc3ccc4c(c3)OCO4)n2)cc1
d: Cc1oc2ccc(O)c(CN3CCOCC3)c2c1C(=O)c1ccc(Cl)cc1
Answer: b. CCOC(=O)CSC1=C(C#N)C(c2ccc(C)cc2)C(C(=O)OC)C(=O)N1
