Problem statement: Answer the multiple-choice question.
Query: Which compound has a 4.414\% 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 other words.
Options:
a: COC(=O)C1=CO[C@H](C)[C@H]2CN3CC[C@@]4(C(=O)Nc5ccccc54)[C@@H]3C[C@H]12
b: COc1cc(C)c(N(C(C)=O)c2ccccc2)c(C)c1
Answer: a. COC(=O)C1=CO[C@H](C)[C@H]2CN3CC[C@@]4(C(=O)Nc5ccccc54)[C@@H]3C[C@H]12
