Task: Answer the MCQ question.
Question: Which compound has a 16.256\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a c1csc(-n2nc3ccccc3n2)c1
b CC(c1cccs1)N(C)Cc1nc(CCc2ccccc2)no1
c COc1ccc(OCCNC(=O)CCCO)cc1
d C=CCOC(=O)C1=C(C)NC(SCC(=O)N(CC)CC)=C(C#N)C1c1ccccc1
e CCCCN1C(Nc2ccccc2)=NC[C@@H]1C
Answer: e. CCCCN1C(Nc2ccccc2)=NC[C@@H]1C
