Task: Answer the multiple choice question.
Query: Which compound exhibits a 21.531% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) C=CCNC(=O)NC(=O)COC(=O)/C=C/c1cccc([N+](=O)[O-])c1
b.) COc1cccc(NC(=O)[C@@H]2CCCN2S(=O)(=O)c2cccc3cccnc23)c1
c.) O=C(Oc1ccc2ccccc2c1)c1ccco1
d.) CC(=O)Oc1ccc2nc(-c3ccc(Br)o3)oc(=O)c2c1
Answer: d. CC(=O)Oc1ccc2nc(-c3ccc(Br)o3)oc(=O)c2c1
