Task: Answer the multiple-choice question.
Question: Which drug has a 17.583\% 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: S=c1[nH]nc(COc2ccccc2)n1/N=C/C=C/c1ccco1
b: O=C(CN(Cc1ccccc1F)C(=O)c1ccco1)NCc1ccc(F)cc1
c: O=C(CCC1CCCCC1)Nc1cccc(C(=O)Nc2ccc(C(=O)O)cc2)c1
d: COC(=O)c1ccccc1CSc1nsc(/C=C/N(C)C)c1C#N
e: OCCC1CN(CCCc2ccccc2)CCN1Cc1ccccc1
Answer: a. S=c1[nH]nc(COc2ccccc2)n1/N=C/C=C/c1ccco1
