Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.996\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a.) CCN1C(=O)NC(c2cc(Br)ccc2OC)C(C(=O)OC)=C1C
b.) COc1ccc(/C=C/C(=O)O)cc1S(=O)(=O)N1CCc2ccccc21
Answer: a. CCN1C(=O)NC(c2cc(Br)ccc2OC)C(C(=O)OC)=C1C
