Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.185\% human ether-à-go-go related gene (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] O=C(O)C1C2C=CC(C2)C1C(=O)NCCc1cccc(Cl)c1
[b] COCN(C#N)c1nc(N(C)C)nc(N(C)C)n1
[c] O=C(COC(=O)c1ccc(CNS(=O)(=O)c2ccc(F)c(Cl)c2)cc1)NCC1CCCCC1
[d] COC(=O)c1c(C)oc(C)c1S(=O)(=O)NC(C)(C)C
Answer: b. COCN(C#N)c1nc(N(C)C)nc(N(C)C)n1
