Critical Reasoning

In recent years, many cabinetmakers have been
winning acclaim as artists. But since furniture must be
useful, cabinetmakers must exercise their craft with an
eye to the practical utility of their product. For this
reason, cabinetmaking is not art.

Which of the following is an assumption that supports
drawing the conclusion above from the reason given
for that conclusion?

(A) Some furniture is made to be placed in
museums, where it will not be used by anyone.

(B) Some cabinetmakers are more concerned than
others with the practical utility of the products
they produce.

(C) Cabinetmakers should be more concerned with
the practical utility of their products than they
currently are.

(D) An object is not an art object if its maker pays
attention to the object's practical utility.

(E) Artists are not concerned with the monetary
value of their products.

OG answer is D ... can someone break this down in detail? Thanks

Premise : Since furniture must be useful, cabinetmakers must exercise their craft with an eye to the practical utility of their product.
Conclusion : cabinetmaking is not art.

A) Some furniture is made to be placed in museums, where it will not be used by anyone. - not a good assumption to conclude that cabinetmaking is not art

B) Some cabinetmakers are more concerned than others with the practical utility of the products they produce. - opposite answer , actually weakens the conclusion

C) Cabinetmakers should be more concerned with the practical utility of their products than they currently are. - Candidate - keep it aside
D) An object is not an art object if its maker pays attention to the object's practical utility. - good assumption , keep it aside
E) Artists are not concerned with the monetary value of their products. - not related

Now take a closer look at Option C & D

C) Cabinetmakers should be more concerned with the practical utility of their products than they currently are.
- It looks like cabinetmakers are already concerned that means some of the furniture is not art which is against the conclusion as conclusion captures all the products that cabinetmakers create. So reject this option

D)An object is not an art object if its maker pays attention to the object's practical utility. - This is your answer.

GREAT RESPONSE! THANKS!
