Task: Answer the multiple-choice question.
Query: What is the hERG inhibition at a concentration of 1uM of a compound with the SMILES O=C(O)C1=C[C@H](c2ccc(Br)cc2)C[C@H](OCCCCO)O1?
Constraint: You must return none, one or more options from a, b, or c without using any other words.
Options:
a: 6.208
b: -10.894
c: 11.960
Answer: a. 6.208\%.
