Problem statement: Answer the multiple-choice question.
Query: Which drug has a 4.630\% 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) COCCN=C1NC(=O)C(CC(=O)Nc2cccc(Cl)c2C)S1
(b) CC1=NN(C(=O)c2nn(C)cc2Br)C(O)(C(F)(F)F)C1
Answer: a. COCCN=C1NC(=O)C(CC(=O)Nc2cccc(Cl)c2C)S1
