Task: Answer the multiple choice question.
Question: Which drug has a -4.152\% 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 other words.
Options:
[a] COc1ccccc1NC(=O)Oc1ccc(C(C)=O)cc1
[b] CCOC(=O)c1ccc2[nH]c(C)c(C)c2c1
[c] COC(=O)c1ccccc1NC(=O)Cn1cnc2cc(C)c(C)cc21
[d] O=C(Cn1nc(-c2ccccc2)ccc1=O)N1CCCCC1
[e] COc1ccc(C(=O)C[n+]2ccccc2/C=N/O)cc1.[Br-]
Answer: d. O=C(Cn1nc(-c2ccccc2)ccc1=O)N1CCCCC1
