Problem statement: Answer the MCQ question.
Question: Which drug has a 12.763\% 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 other words.
Options:
[a] Cc1cc2c(c(=O)n1C)C(C(C)C)C(C#N)=C(N)O2
[b] COCCN(C(=O)COC(=O)c1cc(C)oc1C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
[c] Cc1ccc(NC(=O)Nc2ccccc2)c(Br)c1
[d] CCn1c(SCCC#N)nnc1-c1ccncc1
Answer: a. Cc1cc2c(c(=O)n1C)C(C(C)C)C(C#N)=C(N)O2
