From the above given statements the venn diagram will be:

Conclusion I: No lacquer is paint.
Some paints are lacquers.
Thus, Conclusion I does not follow.

Conclusion II: No lacquer is fresco.
No fresco is lacquer, which is logically equivalent to "No lacquer is fresco."
Thus, Conclusion II logically follows.

Conclusion III: Some frescos are paints.
No paint is fresco, meaning there is no overlap between paints and frescos.
Thus, Conclusion III does not follow.

Conclusion IV: All lacquers are paints.
Statement 1 says some paints are lacquers, but there is no information that implies all lacquers are paints.
Thus, Conclusion IV does not follow.
