Task: Answer the multiple-choice question.
Question: Which drug has a -0.841\% 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(N/N=C/c1ccc[nH]1)c1ccc(COc2cccc3cccnc23)cc1
b CCCCC(=O)Nc1ccc(S(=O)(=O)Nc2nccc(C)n2)cc1
c O=[N+]([O-])c1cc(CN2CCCC2)c2cccnc2c1O
Answer: c. O=[N+]([O-])c1cc(CN2CCCC2)c2cccnc2c1O
