Task: Answer the multiple choice question.
Question: Which drug exhibits a 4.245\% human ether-à-go-go related gene (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] COc1cc(/C=N/NC(=O)C(=O)NCC2CCCO2)ccc1O
[b] CCCC12CN(C(=O)c3ccc([N+](=O)[O-])cc3)CC(C)(CN(C(=O)c3ccc([N+](=O)[O-])cc3)C1)C2=O
[c] CCOc1cc(/C=N/Nc2ccc(C(=O)O)cc2)ccc1OC(=O)c1ccccc1C
[d] CCOC(=O)c1c(C)[nH]c(C(=O)N/N=C\c2ccccc2O)c1C
Answer: d. CCOC(=O)c1c(C)[nH]c(C(=O)N/N=C\c2ccccc2O)c1C
