Task: Answer the multiple-choice question.
Question: Which compound exhibits a 5.345\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) Cc1ccc(N2C(=O)C3CC3C2=O)cc1
b) CCC(=NCc1cc(OC)cc(OC)c1)c1c(O)[nH]c(=O)[nH]c1=O
c) CC1(C)CC(N2CCN(c3ccccc3)CC2)=CC(=[N+]2CCCC2)C1.[I-]
