Task: Answer the multiple choice question.
Question: Which drug has a 16.923% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] COC(=O)/C(=C1\Oc2ccc(C(C)(C)C)cc2S1)C(F)(F)F
[b] O=C(CSc1nnc(COc2ccccc2)o1)N1CCCCC1
Answer: b. O=C(CSc1nnc(COc2ccccc2)o1)N1CCCCC1
