Task: Answer the multiple choice question.
Question: Which compound exhibits a 14.236\% 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 additional words.
Options:
[a] CCN(CC)C(=O)CN1C(=O)C2CC=C(Cl)CC2C1=O
[b] CC(=O)c1c(N)c(C#N)c(C)n1-c1ccc(Br)cc1
[c] Cc1c(C(=O)N2CCCCC2)sc(N)c1C#N
[d] O=C(Nc1cccc(Cl)c1)c1ccncc1
Answer: b. CC(=O)c1c(N)c(C#N)c(C)n1-c1ccc(Br)cc1
