Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.136\% 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) O=C(Cn1c(=O)oc2ccccc21)Nc1ccccc1Cl
(b) CC(C)(C)NC(=O)CSc1nc(N)c(-c2ccccc2)c(=O)[nH]1
(c) COC(=O)Cc1c(C)nc2nc(-c3ccc(OC)cc3)[nH]n2c1=O
Answer: a. O=C(Cn1c(=O)oc2ccccc21)Nc1ccccc1Cl
