According to karl marx, what gives an item its value?
a. demand for the item
b. raw materials that the item is made of
c. labor to create the item
d. capital invested in producing the item

According to Karl Marx, an item has increased value based from the labor to create the item (option C). An item's value is measured objectively based from the number of hours done or required on producing such commodity. For example, if producing shoes takes twice as long as producing pants, then shoes are twice as valuable than pants.
