Task: Answer the MCQ question.
Question: Which drug has a 5.503\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CCCCOCCCN1C(C)=CC(=C2C(=O)NC(=S)NC2=O)C=C1C
[b] O=C(NCc1ccc(F)cc1)c1ccc(CNc2c(N3CCOCC3)c(=O)c2=O)cc1
[c] Cc1nnc(C)n1/N=C/c1ccc(-c2ccccc2Cl)o1
Answer: a. CCCCOCCCN1C(C)=CC(=C2C(=O)NC(=S)NC2=O)C=C1C
