Task: Answer the multiple choice question.
Question: Which drug has a 15.469\% human ether-à-go-go related gene (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. COc1ccc(NCc2cccnc2)cc1
b. O=C(CCNC(=O)c1ccc([N+](=O)[O-])cc1)Nc1nccs1
c. CCc1ccccc1NC(=O)c1ccc(S(=O)(=O)NCC2CCCO2)cc1
d. O=[N+]([O-])c1cccc(C(=NCc2ccccc2)NO)c1
e. COc1ccccc1NS(=O)(=O)c1cc(C(=O)NCC2CCCO2)ccc1C
Answer: d. O=[N+]([O-])c1cccc(C(=NCc2ccccc2)NO)c1
