Task: Answer the MCQ question.
Question: Which compound has a 20.349\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CC(=O)C1=C(C)NC(SCC(N)=O)=C(C#N)C1CC(C)C
b: Cc1ccc2c(c1)N(CC(=O)N1CCCC1)C(=O)C(C)O2
c: O=C(Cc1cccs1)Nc1cccc(-c2nc3ccccc3[nH]2)c1
d: O=C(Nc1ccccc1)c1ccc(-n2cnnn2)cc1
Answer: a. CC(=O)C1=C(C)NC(SCC(N)=O)=C(C#N)C1CC(C)C
