Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.044% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CCOc1ccc2nc(NCCNC(=O)Nc3ccccc3)c(C#N)cc2c1
b CCc1[nH]nc2c1C(c1cccc(OC(=O)N3CCOCC3)c1)C(C#N)=C(N)O2
c CC(=O)Nc1ccc(-c2csc(NC(=O)C3CC(=O)N(c4ccc5c(c4)OCCO5)C3)n2)cc1
d CCN1CCSc2ccc(C(=O)NCc3cccc(Br)c3)cc21
Answer: d. CCN1CCSc2ccc(C(=O)NCc3cccc(Br)c3)cc21
