Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.636\% 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(COC(=O)c1cccnc1Nc1ccccc1F)NCCN1C(=O)CSC1=O
b) CCOc1ccccc1C1C(C(=O)Nc2ccc(OC)cc2)=C(C)Nc2nc(CCCO)nn21
Answer: b. CCOc1ccccc1C1C(C(=O)Nc2ccc(OC)cc2)=C(C)Nc2nc(CCCO)nn21
