Task: Answer the multiple choice question.
Question: Which drug has a -16.194\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COc1ccccc1/C=N\N=C(\N)c1ccccn1
[b] Cc1ccc(CN2CCN(CC(=O)N3CCC4(CC3)OCCO4)C2=O)cc1
