Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 5.114\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCSC1(SCC)N=C(N)C2(C#N)C(c3ccccc3)NC(C)=CC12C#N
b: Cc1nn(-c2ccccc2)c(Cl)c1C1C(C#N)=C(N)OC2=C1C(=O)CC(C)(C)C2
Answer: b. Cc1nn(-c2ccccc2)c(Cl)c1C1C(C#N)=C(N)OC2=C1C(=O)CC(C)(C)C2
