Problem statement: Answer the multiple choice question.
Query: Which drug has a 18.130\% 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: CCOc1cc(/C=N/N=C2/NC(=O)C(CC(=O)O)S2)ccc1OCc1ccc(Cl)cc1Cl
b: CCN(CC)c1c2c(c(C#N)c3nc4ccccc4n13)CCC2
c: CCc1ccc(S(=O)(=O)n2c(C)nc3ccccc32)cc1
Answer: c. CCc1ccc(S(=O)(=O)n2c(C)nc3ccccc32)cc1
