Problem statement: Answer the multiple choice question.
Question: Which compound has a 2.152\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=c1c2c3nc4ccccc4nc3n(CC3CCCO3)c2ncn1CCc1ccccc1
(b) O=S(=O)(N1CCOCC1)N1CCCN(S(=O)(=O)N2CCOCC2)CC1
(c) CCCN(CCC)S(=O)(=O)c1ccc(N2CCCC2=O)c([N+](=O)[O-])c1
(d) CS(=O)(=O)c1ccc(C(=O)OCc2nnc(-c3ccc(Cl)cc3)o2)cc1[N+](=O)[O-]
Answer: b. O=S(=O)(N1CCOCC1)N1CCCN(S(=O)(=O)N2CCOCC2)CC1
