Task: Answer the multiple choice question.
Question: Which drug has a 20.153\% 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 CCOCCCn1cnc2c[n+](CC(=O)c3ccccc3)cc(Br)c21.[Br-]
b Cc1ccc(/C(O)=C2\C(=O)C(=O)N(c3cc(C)on3)C2c2cccc(Cl)c2)cc1
c Cc1cc(Cl)c(S(=O)(=O)NC2CCCC2)cc1OCC(N)=O
Answer: a. CCOCCCn1cnc2c[n+](CC(=O)c3ccccc3)cc(Br)c21.[Br-]
