Task: Answer the multiple-choice question.
Query: Which drug has a 0.007\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] Cc1ccc(-n2c(O)c(C=NCCC3=CCCCC3)c(=O)[nH]c2=O)cc1
[b] CCOC(=O)C1=C(COC(=O)Cc2ccc(Cl)cc2)NC(=O)NC1C
[c] CN(C)C(=O)C[n+]1cccc(/C=N/O)c1
[d] CC(=O)Oc1ccc(C)cc1-n1nc2ccccc2n1
[e] Cn1cc(SCC(=O)NCc2ccc3c(c2)OCO3)c2ccccc21
Answer: b. CCOC(=O)C1=C(COC(=O)Cc2ccc(Cl)cc2)NC(=O)NC1C
