Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 14.486\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CCN1C(=O)N[C@@H](c2ccccc2)[C@H](C(C)=O)[C@H]1C
b C=C(C(=O)O)C(CCCCCC)C(=O)O
c COC(=O)NNC(=O)C(c1ccccc1)c1ccccc1
Answer: a. CCN1C(=O)N[C@@H](c2ccccc2)[C@H](C(C)=O)[C@H]1C
