Task: Answer the MCQ question.
Question: Which drug has a 1.492% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] C=CCn1c(O)c(C(C)=Nc2ccc(N(C)C)cc2)c(=O)[nH]c1=O
[b] O=C(CCc1nnc(CCc2c[nH]c3ccccc23)o1)NC1CCC1
[c] CCOC(=O)C1(Cc2ccc(Cl)cc2)CCN(C(=O)C2=NNC(=O)CC2)CC1
[d] COC(=O)Cn1cnc2c(cnn2-c2ccccc2)c1=O
Answer: d. COC(=O)Cn1cnc2c(cnn2-c2ccccc2)c1=O
