Task: Answer the multiple-choice question.
Query: Which compound exhibits a 11.788\% 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(CSc1ccccc1)N[C@@H](Cc1ccccc1)C(=O)O
b: O=C(OCc1nnc(-c2ccccc2)o1)c1cc(Cl)ccc1[N+](=O)[O-]
Answer: a. O=C(CSc1ccccc1)N[C@@H](Cc1ccccc1)C(=O)O
