Problem statement: Answer the multiple choice question.
Query: Which drug has a 8.577\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] CCCCN(C(=O)NC(=O)Nc1cc(C)ccc1C)S(C)(=O)=O
[b] Cc1noc(C)c1S(=O)(=O)NCCCN1CCN(Cc2ccccc2)CC1
[c] CCCCOc1ccc(CN=C(N)N)cc1Cl
[d] CCOC(=O)c1ccccc1NC(=O)CSc1ncc(C(=O)OCC)c(N)n1
[e] O=c1cc(CSc2nnc(COc3ccc(Cl)cc3)o2)c2ccccc2[nH]1
Answer: c. CCCCOc1ccc(CN=C(N)N)cc1Cl
