Task: Answer the multiple-choice question.
Question: Which drug exhibits a -44.157\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCCCN1C(Nc2ccccc2)=NC[C@@H]1Cc1ccccc1
(b) CCc1c(C)nc(N)n2c(SCC(=O)Nc3ccccc3OC)nnc12
Answer: a. CCCCN1C(Nc2ccccc2)=NC[C@@H]1Cc1ccccc1
