Task: Answer the multiple-choice question.
Question: Which compound has a 4.037\% 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 CCC(CO)N=CC1=C(O)C(C(=O)c2ccccc2)CCC1=O
b O=C(COc1ccccc1Br)N1CCN(C(=O)c2ccco2)CC1
c CCCCNC(=O)Cn1c(=O)oc2cc(S(=O)(=O)N3CC(C)CC(C)C3)ccc21
d CC(OC(=O)c1cccc(-n2cnnn2)c1)C(=O)Nc1ccc(F)cc1Cl
e CC(C)COC(=O)/C(C#N)=C/c1c[nH]c2ccccc12
Answer: b. O=C(COc1ccccc1Br)N1CCN(C(=O)c2ccco2)CC1
