Task: Answer the multiple-choice question.
Question: Which compound exhibits a 5.987% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CCN(CC)S(=O)(=O)c1ccc(C)c(NC(=O)COC(=O)c2ccc(C)c(S(=O)(=O)N3CCOCC3)c2)c1
b) O=C(NCc1nc2ccccc2[nH]1)C1=C[C@H](C2CCCCC2)C[C@H](OCc2ccc(CO)cc2)O1
Answer: b. O=C(NCc1nc2ccccc2[nH]1)C1=C[C@H](C2CCCCC2)C[C@H](OCc2ccc(CO)cc2)O1
