Task: Answer the MCQ question.
Query: Which compound has a 11.998\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCN(Cc1ccncc1)Cc1ccc(Br)cc1.O=C(O)C(=O)O
[b] COc1ccc(C2C=C(C)Nc3nc4ccccc4n32)cc1
[c] CC(=O)Oc1c(C)c(OC(C)=O)c2c(c1C(C)=O)OC1CC(=O)C(C(C)=O)=C(O)C21C
