Which renaissance master produced the work shown here?

a.
donatello

b.
giotto

c.
michelangelo

d.
van eyck

I believe that the picture represents one of Donatello's statues, 'The Bronze David'.

This version of David is the second one which is made of bronze. The first version of David was carved out of marble. No, this is not the David statue that Michelangelo made - this is Donatello's version of David. 

So, considering that Donatello created the bronze David, the answer is A) Donatello.

Ifound this on google “the existence of agglomeration economies is central to the explanation of how cities increase in size and population, which places the phenomenon on a larger scale. the concentration of economic activity in cities is one reason for their development and growth.” i hope this you for what your looking for.
