Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -30.977\% 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: Cn1c(CN2CCCC2)nc2cc(NS(=O)(=O)c3ccc(Cl)cc3)ccc21
b: Nn1cc(-c2ccccc2)nc1SCC(=O)N1CCN(S(=O)(=O)c2ccccc2)CC1
c: CCCc1cc(=O)oc2cc(C)cc(OCc3nn[nH]n3)c12
Answer: a. Cn1c(CN2CCCC2)nc2cc(NS(=O)(=O)c3ccc(Cl)cc3)ccc21
