Task: Answer the multiple choice question.
Query: Which drug has a -2.512\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a COc1cc(/C=C2\C(=N)N3N=C(S(C)(=O)=O)SC3=NC2=O)ccc1OS(=O)(=O)c1ccc(C)cc1
b Cc1c(CCC(=O)O)c(=O)n2c([nH]c3ccccc32)c1C#N
c Cc1ccccc1CNS(=O)(=O)c1ccccc1[N+](=O)[O-]
Answer: b. Cc1c(CCC(=O)O)c(=O)n2c([nH]c3ccccc32)c1C#N
