Task: Answer the multiple choice question.
Question: Which compound exhibits a 18.786% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CC(/C=C/c1ccco1)=N\NC(=O)C(O)c1ccccc1
b O=C(O)C1CCC(CNCc2ccncc2)CC1
c Cc1cccc(NC(=O)CN2CCN(C(=O)C3CCCO3)CC2)c1C
d O=C(Nc1nccs1)c1ccccc1N=Cc1ccccc1
Answer: b. O=C(O)C1CCC(CNCc2ccncc2)CC1
