Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.655\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(C1COc2ccccc2O1)N1CCN(c2nc3ccc([N+](=O)[O-])cc3s2)CC1
[b] Nn1cnnc1SCC(=O)Nc1ccc(C2CCCCC2)cc1
[c] NC(=O)NC(=O)COC(=O)/C=C/c1cccs1
[d] COc1ccc(N=Cc2c(O)n(C)c(=O)[nH]c2=O)cc1
Answer: d. COc1ccc(N=Cc2c(O)n(C)c(=O)[nH]c2=O)cc1
