Task: Answer the multiple choice question.
Question: Which drug exhibits a 10.835\% 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) C=CCN(CC=C)C(=O)CN1C(=O)NC(C)(c2ccc3cc(OC)ccc3c2)C1=O
(b) COC(=O)Cn1c(=NC(=O)c2nc3ccccc3s2)sc2cc(S(N)(=O)=O)ccc21
Answer: b. COC(=O)Cn1c(=NC(=O)c2nc3ccccc3s2)sc2cc(S(N)(=O)=O)ccc21
