Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.770\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCN1CCN(S(=O)(=O)c2ccc3c(c2)NC(=O)CS3)CC1
[b] O=C(NC1CCCCC1)C(c1cccs1)N(C(=O)c1ccco1)c1ccc2c(c1)OCCO2
[c] O=C(NCc1ccccc1)C1=C[C@H](C2CCCCC2)C[C@H](OCc2ccc(CO)cc2)O1
Answer: c. O=C(NCc1ccccc1)C1=C[C@H](C2CCCCC2)C[C@H](OCc2ccc(CO)cc2)O1
