Task: Answer the multiple choice question.
Query: Which drug has a -1.214\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=C(O)c1ccccc1N=Nc1ccc(O)cc1
b) CCc1ccccc1NC(=S)/N=C(\N)Nc1nc(C)c2cc(C)ccc2n1
c) CCCNC(=O)C(Cc1ccccc1)NC(=O)c1ccc(C(C)(C)C)cc1
Answer: b. CCc1ccccc1NC(=S)/N=C(\N)Nc1nc(C)c2cc(C)ccc2n1
