Problem statement: Answer the multiple-choice question.
Query: Which drug has a 5.419\% 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(C1CCCN(S(=O)(=O)c2cnc[nH]2)C1)N1CC(=O)N(CCc2ccccc2)C(=O)C1
b O=S1(=O)CCOC[C@H](CC2CCCCC2)N1Cc1ccc(Cl)cc1
Answer: a. O=C(C1CCCN(S(=O)(=O)c2cnc[nH]2)C1)N1CC(=O)N(CCc2ccccc2)C(=O)C1
