Task: Answer the multiple-choice question.
Question: Which drug has a 0.510\% 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 other words.
Options:
a: CN(c1ccc(Cl)cc1)c1cc(=O)n(C)c2ccccc12
b: CCOc1ccc(OCCSc2nnnn2-c2ccccc2)cc1
c: O=C(COc1ccccc1)N/N=C/c1cccc2cccnc12
d: O=C(COn1nnc2ccc(Cl)cc21)NCc1ccccc1
Answer: d. O=C(COn1nnc2ccc(Cl)cc21)NCc1ccccc1
