Task: Answer the MCQ question.
Query: Which drug has a 19.723% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) COc1cc(-n2nc(C)c3c2OC(N)=C(C#N)C3c2ccccc2)c(Cl)c(Br)c1O
(b) COc1ccc(NC(=O)c2cc(-c3cccc(OC)c3)on2)cc1
(c) CCN(CC)C(=O)CSC(Nc1cccc(F)c1)=C(C#N)C#N
(d) C=CCN1C(=O)NC(=O)/C(=C/c2ccc(OC)c(COc3ccc(NC(C)=O)cc3)c2)C1=O
(e) CCOC(=O)C1CCCN(C(=O)c2ccc3c(c2)NC(=O)C(N2CCOCC2)S3)C1
Answer: e. CCOC(=O)C1CCCN(C(=O)c2ccc3c(c2)NC(=O)C(N2CCOCC2)S3)C1
