Dürer's two written works regarding art are a. dürer's philosophy and human perspective b. monumental perspective and landscape composition c. linear perspective and musculature design d. treatise on measurement and four books on human proportions

I believe the correct answer is D. Treatise on Measurement and Four Books on Human Proportions.

Albrecht Dürer was a painter, printmaker, and theorist of the German Renaissance. He wrote two theoretical books – “Four Books on Measurement” and “Four books on Human Proportion” which are reinforced by his theoretical treatises, involving principles of mathematics, perspective, and ideal proportions. These book were written in German rather than Latin, which contributed to the expansion in German prose which Martin Luther had begun with his translation of the "Bible".
