Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 17.766\% 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: Cc1cccc(C(=O)N/N=C/c2coc3ccccc3c2=O)c1
b: Cc1cc(C(F)(F)F)n(-c2nc(-c3nnc(SCc4ccc(C(F)(F)F)cc4)n3C)cs2)n1
c: COC(=O)c1ccc(C(=O)OC)c(NC(=O)CS(=O)(=O)Cc2ccccc2)c1
d: O=C(Nc1ccc2nccnc2c1)c1cnccn1
e: CCN(CC(=O)NCc1ccc(Cl)cc1)C(=O)COc1ccc(C)cc1C
Answer: d. O=C(Nc1ccc2nccnc2c1)c1cnccn1
