Task: Answer the multiple choice question.
Question: Which compound has a 7.653\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CCOc1nc(CC(C)C)c2c(c1C#N)CC(C)(C)OC2
(b) Cc1ccnc(NS(=O)(=O)c2ccc(NC(=O)c3ccc4c(c3)OCCO4)cc2)n1
(c) O=C(Cn1c(-c2ccccc2)c(-c2ccccc2)[nH]c1=S)c1ccccc1
Answer: a. CCOc1nc(CC(C)C)c2c(c1C#N)CC(C)(C)OC2
