Task: Answer the multiple choice question.
Query: Which compound has a 6.475\% 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. CC1=C(C#N)C(c2ccccc2O)C(C#N)=C(C)N1
b. O=S(=O)(Cc1ccccc1)c1nc2ccccc2n1Cc1ccccn1
c. O=C(COC(=O)c1ccc(S(=O)(=O)N2CCOCC2)cc1)Nc1nc(-c2ccccc2)cs1
d. Cc1c(C(=O)N2CCCC2)sc(NC(=O)c2ccco2)c1C#N
e. O=C(CCC(=O)c1cccs1)NNC(=O)c1ccccc1O
Answer: b. O=S(=O)(Cc1ccccc1)c1nc2ccccc2n1Cc1ccccn1
