Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 15.580\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. C=CCOC(=O)C1=C[C@@H](c2ccc(Br)cc2)[C@H](CCCO)[C@@H](OCC)O1
b. CC(/C=C/c1ccco1)=N/NC(=O)Cc1cccs1
c. Cn1ncc(C#N)c1/N=C/N1CCCCC1
Answer: a. C=CCOC(=O)C1=C[C@@H](c2ccc(Br)cc2)[C@H](CCCO)[C@@H](OCC)O1
