Task: Answer the multiple choice question.
Query: Which compound exhibits a 21.595% human ether-à-go-go related gene (hERG) inhibition at 10uM?
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](c2ccco2)C(C(C)=O)=C1C
[b] COc1ccc(CN(C)C(=O)Cc2c[nH]c3ccccc23)c(OC)c1OC
[c] Cc1ccc(SC2=C(C(=O)O)CCCC2)cc1
Answer: a. CCN1C(=O)N[C@@H](c2ccco2)C(C(C)=O)=C1C
