Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.253\% 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 C/C(Cc1ccccc1)=N/NC(=O)CCCC(=O)N/N=C(/C)Cc1ccccc1
b O=C(Nc1cccc(F)c1)N1CCC(n2c(=O)[nH]c3ccccc32)CC1
Answer: b. O=C(Nc1cccc(F)c1)N1CCC(n2c(=O)[nH]c3ccccc32)CC1
