Task: Answer the multiple choice question.
Query: Which compound has a 11.252\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] Cc1onc(-c2c(F)cccc2Cl)c1C(=O)Nc1nc2c(s1)CCCC2
[b] COc1ccc(C(N)=S)c(OC)c1
[c] O=C(COC(=O)c1ccncc1)c1ccc(Br)cc1
Answer: c. O=C(COC(=O)c1ccncc1)c1ccc(Br)cc1
