Task: Answer the multiple-choice question.
Question: Which compound exhibits a 0.726\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) CCCCn1c(-c2ccccc2C)nc2cc3[nH]c(=O)c(C(C)C)nc3cc21
b.) CCOc1ccc(-c2[nH]nc3c2C(c2cccnc2)C(C#N)=C(N)O3)cc1
c.) CC(Oc1cccc2ccccc12)C(=O)N/N=C/c1cccnc1
Answer: b. CCOc1ccc(-c2[nH]nc3c2C(c2cccnc2)C(C#N)=C(N)O3)cc1
