Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.161\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(-c2nn3c(-c4ccco4)nnc3s2)cc1OC
b: O=S(=O)(NCc1ccccc1)c1ccc(Br)s1
c: CCOC(=O)CN(C)Cc1c[nH]c2ccccc12
Answer: b. O=S(=O)(NCc1ccccc1)c1ccc(Br)s1
