Task: Answer the multiple-choice question.
Question: Which compound exhibits a 20.907% 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] COC(=O)c1ccc(NC(=O)CCS(=O)(=O)c2ccc(Br)cc2)cc1
[b] Cc1onc(-c2ccccc2)c1C(=O)Nc1cc(C(F)(F)F)ccc1N1CCOCC1
[c] O=C(O)C(Oc1ccc2c(c1)oc(=O)c1ccccc12)c1ccccc1
Answer: c. O=C(O)C(Oc1ccc2c(c1)oc(=O)c1ccccc12)c1ccccc1
