Task: Answer the multiple-choice question.
Query: Which drug has a 19.621\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) CCOC(=O)CC1=C(C(=O)OCC)C(c2cc(OC)c(OC)cc2OC)C(C#N)=C(N)O1
(b) O=C(O)c1ccccc1NC(c1ccccc1)c1ccc(Cl)cc1
(c) Cc1ccc(CS/C(Nc2ccccc2C)=C(\C#N)C(=O)NCc2ccco2)c(C)c1
(d) Cc1[nH]c2ccccc2c1SCC(=O)N1CCCCCC1
(e) Cc1ccc(N2C(=O)/C(=C/c3cccnc3)SC2=S)cc1
Answer: b. O=C(O)c1ccccc1NC(c1ccccc1)c1ccc(Cl)cc1
