Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.054\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Cc1cc2c(c(=O)o1)C(CCC1CCCCC1)C(C#N)=C(N)O2
b: O=C(O)C(=O)O.c1ccc(-c2ccccc2OCCOCCN2CCNCC2)cc1
Answer: b. O=C(O)C(=O)O.c1ccc(-c2ccccc2OCCOCCN2CCNCC2)cc1
