Task: Answer the MCQ question.
Question: Which compound has a 7.432\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C(NNC(=O)c1cccc2ccccc12)c1ccccc1O
[b] CCOC(=O)C1=CC[C@@H](c2ccco2)N(S(=O)(=O)c2ccc(C)cc2)[C@H]1C(=O)OCC
[c] COc1cc(S(=O)(=O)N2CCOCC2)c(OC)c(S(=O)(=O)N2CCOCC2)c1
Answer: a. O=C(NNC(=O)c1cccc2ccccc12)c1ccccc1O
