Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.624\% 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(CCc1ccccc1)NC(=S)Nc1cccc(C(=O)O)c1
b: O=C(CN(c1ccccc1)S(=O)(=O)c1ccccc1[N+](=O)[O-])N1CCCC1
Answer: a. O=C(CCc1ccccc1)NC(=S)Nc1cccc(C(=O)O)c1
