Task: Answer the MCQ question.
Query: Which drug exhibits a 3.106\% 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 additional words.
Options:
[a] O=C(NC1CC1)C1=C[C@@H](c2ccc(Br)cc2)C[C@@H](OCc2ccc(CO)cc2)O1
[b] Cn1c(=O)c2[nH]c(Nc3ccccc3)nc2n(C)c1=O
[c] Cc1nc2nc(-c3cccs3)[nH]c2cc1Br
Answer: b. Cn1c(=O)c2[nH]c(Nc3ccccc3)nc2n(C)c1=O
