Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.186\% 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) COc1ccc(CN2C(=O)CS(=O)CC2=O)cc1OC
(b) COCC1CCCCN1C(=O)c1cccc(OC2CCN(C(=O)C3CC3)CC2)c1
(c) CCn1c(C)cc2c(c1=O)C(c1ccccc1)C(C(=O)OC)=C(N)O2
Answer: a. COc1ccc(CN2C(=O)CS(=O)CC2=O)cc1OC
