Task: Answer the multiple choice question.
Query: Which compound has a 3.767\% 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. O=C(NNC(=O)c1cccs1)Nc1cccc(Cl)c1
b. CSCC[C@H](NC(=O)OC(C)(C)C)c1nnc(SCC=C(C)C)o1
Answer: a. O=C(NNC(=O)c1cccs1)Nc1cccc(Cl)c1
