Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.578\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(CSc1nnc(-c2ccco2)o1)c1ccccc1
b: CCc1ccc2[nH]c(=O)c(CN(Cc3ccc4c(c3)OCO4)Cc3nnnn3C3CCCC3)cc2c1
Answer: a. O=C(CSc1nnc(-c2ccco2)o1)c1ccccc1
