Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.291\% 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. CC(C)(C)CN1C(N)=NC[C@H]1Cc1ccc(O)cc1
b. O=C(CSC(=S)N1CCCC1)Nc1ccc(Br)cc1Cl
Answer: a. CC(C)(C)CN1C(N)=NC[C@H]1Cc1ccc(O)cc1
