Task: Answer the multiple choice question.
Query: Which compound exhibits a -4.775\% 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 or b without using any additional words.
Options:
a. CCOC(=O)c1ccc(S(=O)(=O)N2CCN(C(C)=O)CC2)cc1
b. C=C(C)c1cccc(C(C)(C)NC(=O)NC(c2ccccc2)c2ccc(OC)cc2)c1
Answer: a. CCOC(=O)c1ccc(S(=O)(=O)N2CCN(C(C)=O)CC2)cc1
