Problem statement: Answer the multiple choice question.
Query: Which drug has a 3.359\% 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) CCCSC1=C(C#N)C(c2ccc(O)c(OC)c2)CC(=O)N1
(b) O=C(COn1nnc2ccc(S(=O)(=O)N3CCOCC3)cc21)NCCc1ccccc1
Answer: a. CCCSC1=C(C#N)C(c2ccc(O)c(OC)c2)CC(=O)N1
