Problem statement: Answer the multiple choice question.
Question: Which compound has a 2.610\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) Cc1cccc(Nc2cc(=O)[nH]c(=O)[nH]2)c1
b) O=C(Cc1ccc(Br)cc1)N1CCc2ccccc2C1
c) CCCCOC(=O)C1=C(C)Nc2ncnn2C1c1ccc(OC)c(OC)c1
d) O=C(c1ccc(Cl)cc1)N1CCOc2ccccc21
Answer: c. CCCCOC(=O)C1=C(C)Nc2ncnn2C1c1ccc(OC)c(OC)c1
