Task: Answer the multiple choice question.
Question: Which drug has a -3.488\% 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 additional words.
Options:
a: CCNc1c(NS(=O)(=O)c2ccc(F)c(Cl)c2)c(=O)oc2ccccc12
b: O=C(O)CC(NC(=O)c1ccc2c(c1)OCO2)c1cccc([N+](=O)[O-])c1
c: CCc1c(C(=O)N2CCOCC2)csc1C
Answer: c. CCc1c(C(=O)N2CCOCC2)csc1C
