Task: Answer the MCQ question.
Question: Which drug exhibits a 20.726\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: C[C@@H](NC(=O)/C(C#N)=C/c1ccc(O)c(O)c1)c1ccccc1
b: CC(/C=N/NC(=O)c1nnn(-c2nonc2N)c1CN(C)C)=C\c1ccco1
c: Cn1c(=O)c([N+](=O)[O-])c(-n2ccnc2)c2ccccc21
d: CCc1ccc(Nc2nc(N)nc(CSc3nnnn3-c3ccccc3)n2)cc1
Answer: d. CCc1ccc(Nc2nc(N)nc(CSc3nnnn3-c3ccccc3)n2)cc1
