Task: Answer the multiple choice question.
Query: Which compound exhibits a 9.400\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(O)CC/C(=C\c1cc2c(cc1Br)OCO2)c1nc2ccccc2s1
b) O=C(CNC(=O)c1ccccc1)NCC(=O)OCC(=O)c1ccc(F)cc1
Answer: a. O=C(O)CC/C(=C\c1cc2c(cc1Br)OCO2)c1nc2ccccc2s1
