Task: Answer the MCQ question.
Question: Which drug exhibits a -19.755% 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] CCOC(=O)c1sc(C)c2c1NC1(CCCCC1)NC2=O
[b] O=C(COC(=O)[C@H](Cc1ccccc1)NC(=O)c1cccs1)NC1CCCCC1
[c] CCOc1ccc(C(Nc2ccc(C)cc2)P2(=O)OCCCO2)cc1
[d] COC(=O)c1c(NC(=O)c2cccc(N3C(=O)CCC3=O)c2)sc2c1CCN(C(C)=O)C2
Answer: a. CCOC(=O)c1sc(C)c2c1NC1(CCCCC1)NC2=O
