Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.241\% 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=C(COC(=O)c1cncc(Br)c1)NC1CCCC1
[b] O=C(CSc1nnc(-c2cccnc2)s1)Nc1cccc(C(=O)O)c1
Answer: b. O=C(CSc1nnc(-c2cccnc2)s1)Nc1cccc(C(=O)O)c1
