Task: Answer the multiple choice question.
Question: Which compound exhibits a 17.567\% 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 CC1=C(C(=O)OCc2ccccc2)C(/C=C/c2ccccc2)N2C(=O)CCSC2=N1
b CCCCc1cc(=O)oc2c(CN3CCCC3)c(O)c(Cl)cc12
c COc1ccc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2c2nnc(C)s2)cc1OC
d Cc1cc(C)cc(OCC(=O)O/N=C(\N)c2ccccn2)c1
e NC(=O)C1CCN(C(=S)c2ccc(-c3ccc(Br)cc3)o2)CC1
Answer: a. CC1=C(C(=O)OCc2ccccc2)C(/C=C/c2ccccc2)N2C(=O)CCSC2=N1
