Task: Answer the multiple choice question.
Query: Which compound exhibits a 0.921\% 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] O=C(NCc1ccccn1)C1C2C=CC(C2)C1C(=O)Nc1ccc(F)cc1
[b] COc1cc(C(=O)Oc2c(OC)cc(C(=S)N3CCOCC3)cc2OC)cc(OC)c1OC
[c] CCOC(=O)C1(Cc2cccc(F)c2)CCN(C(=O)C2CCOCC2)CC1
Answer: a. O=C(NCc1ccccn1)C1C2C=CC(C2)C1C(=O)Nc1ccc(F)cc1
