Problem statement: Answer the multiple-choice question.
Question: Which compound has a 3.430\% 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] O=C(N/N=C/c1ccc(Br)o1)c1ccc2c(c1)OCCO2
[b] N#CCCN1CCN(S(=O)(=O)c2cc(Cl)ccc2Cl)CC1
[c] O=C(CSc1n[nH]c(=O)[nH]c1=O)c1ccc([N+](=O)[O-])cc1
Answer: c. O=C(CSc1n[nH]c(=O)[nH]c1=O)c1ccc([N+](=O)[O-])cc1
