Task: Answer the multiple choice question.
Question: Which drug exhibits a -6.575% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCn1cc(S(=O)(=O)c2ccc(C)cc2)c(=O)c2cc(OC)ccc21
b: CCCCn1c(SCC(=O)OCC)nc2c1c(=O)[nH]c(=O)n2C
c: O=[N+]([O-])c1ccc2oc(-c3cccc(O)c3)nc2c1
Answer: c. O=[N+]([O-])c1ccc2oc(-c3cccc(O)c3)nc2c1
