Task: Answer the multiple-choice question.
Question: Which drug has a 16.356\% 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] COc1cc(/C=N/Nc2ccc(Cl)c(C(=O)O)c2)ccc1OCC(=O)N1C(C)CCCC1C
[b] O=C(NNC(=O)c1cc2ccccc2cc1O)NC1CCCCC1
[c] Cc1c(NCc2nc3ccccc3[nH]2)c(=O)n(-c2ccccc2)n1C.Cl
Answer: b. O=C(NNC(=O)c1cc2ccccc2cc1O)NC1CCCCC1
