Task: Answer the multiple-choice question.
Query: Which compound has a 2.052% 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 or b without using any additional words.
Options:
a) COc1ccc(Cl)cc1NC(=O)C/C(C)=N/NC(=O)CC#N
b) O=C(O)/C=C/C(=O)c1ccc(O)cc1
Answer: b. O=C(O)/C=C/C(=O)c1ccc(O)cc1
