Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.298\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1cc2c(cc1OC)C(c1cccc([N+](=O)[O-])c1)=NCC2
b: COc1cc(/C=N/NC(=O)C(=O)NCc2ccco2)cc(Br)c1O
c: C/C(=N/OC(=O)N(C)C)c1ncc(C(F)(F)F)cc1N1CCOCC1
d: Nc1nc(-c2cccnc2)nn1C(=O)CCc1ccccc1
Answer: d. Nc1nc(-c2cccnc2)nn1C(=O)CCc1ccccc1
