Task: Answer the multiple choice question.
Query: Which compound exhibits a 4.566\% 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 COc1ccc(CN2CCNC(=O)C2CC(=O)N(C)Cc2ccon2)cc1OC
b C/C(=N\Nc1ccc(C(=O)c2c(C)cc3ccccn23)cc1[N+](=O)[O-])c1ccc(O)cc1
c Cn1c(N)c(C(=O)COC(=O)C2CCCN2C(=O)c2cccs2)c(=O)n(C)c1=O
d CCOc1ccccc1N(CC(=O)NC1CCCCC1)S(=O)(=O)c1ccc(C)cc1
Answer: a. COc1ccc(CN2CCNC(=O)C2CC(=O)N(C)Cc2ccon2)cc1OC
