Task: Answer the multiple choice question.
Query: Which compound has a 0.111\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=Cc1c(SCCO)nc2ccccn2c1=O
b. O=C(COCc1cc(-c2ccco2)on1)NC1CCCCC1
Answer: a. O=Cc1c(SCCO)nc2ccccn2c1=O
