Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -2.148% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] C=CCNc1nc(N)c([N+](=O)[O-])c(NCCO)n1
[b] COc1ccc(C2C(C#N)=C(N)Oc3n[nH]c(C)c32)cc1CN1CCN(c2ccc(F)cc2)CC1
[c] O=C(CN1C(=O)NC2(CCCC2)C1=O)NNC(=O)c1ccc(F)cc1
[d] Cn1cc(CCC(=O)N2CCCC(C(=O)c3ccc(C(C)(C)C)cc3)C2)cn1
[e] CC(c1ccon1)N(C)Cc1cn[nH]c1-c1ccc(F)cc1F
Answer: a. C=CCNc1nc(N)c([N+](=O)[O-])c(NCCO)n1
