Task: Answer the multiple choice question.
Query: Which drug has a 14.180\% 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. Cc1ccc(CN(C)C(=O)CN2C(=O)NC3(CCCc4ccccc43)C2=O)c(C)c1
b. NC(=O)C1=C[C@@H](C2CCCCC2)C[C@@H](OCCCCO)O1
Answer: b. NC(=O)C1=C[C@@H](C2CCCCC2)C[C@@H](OCCCCO)O1
