Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 6.784\% 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] Cc1cc(=O)[nH]c(SCc2cccc(Br)c2)n1
[b] Brc1cc2[nH]cnc2c2ccccc12
[c] CCCc1[nH]nc2c1C(c1c(C)nn(-c3ccccc3)c1Cl)C(C#N)=C(N)O2
Answer: a. Cc1cc(=O)[nH]c(SCc2cccc(Br)c2)n1
