Problem statement: Answer the multiple-choice question.
Query: Which compound has a 8.027\% 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, or d without using any other words.
Options:
a: CCC1(C)N([O-])C(C)=C(c2ccccc2)[N+]1=O
b: Cc1cc(/C=N\NC(=O)COc2cccc3cccnc23)c(C)n1-c1ccccc1
c: NC(=O)CC(NC(=O)Cc1ccc(Br)cc1)c1ccc(NC2CC3CCC2C3)c([N+](=O)[O-])c1
d: CCS(=O)(=O)c1ccc2c(c1)N(S(C)(=O)=O)CC(C(=O)NC1CC1)O2
Answer: a. CCC1(C)N([O-])C(C)=C(c2ccccc2)[N+]1=O
