Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -4.446\% 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 additional words.
Options:
[a] CCc1c(C)sc(NC(=O)c2cccs2)c1C(N)=O
[b] Cc1oc2c(CN3CCCC3)c(O)ccc2c(=O)c1-c1ccccc1
[c] COC(=O)C1=C(C)NC(C)=C(C(=O)OCC(C)C)C1c1ccccc1[N+](=O)[O-]
[d] COc1cc(OC)c(OC)cc1/C=N/Nc1ncnc2c1[nH]c1ccccc12
Answer: d. COc1cc(OC)c(OC)cc1/C=N/Nc1ncnc2c1[nH]c1ccccc12
