Option 1 -> Consumption goods are directly used by households for satisfaction of wants, not machines.
Option 2 -> Normal goods refer to demand theory where demand increases with income, not relevant here.
Option 3 -> Intermediate goods are used up in production (like raw materials), but machines are capital assets.
Option 4 -> Machines are capital goods counted as investment in GDP, making them final goods.
Hence, Final goods -> Machines produced in an economy are classified as capital goods, which are a category of final goods. Unlike intermediate goods that are consumed during production, machines are fixed assets that facilitate production over multiple periods. In national income accounting, they are counted as Gross Fixed Capital Formation (investment) and form part of GDP. They are not consumed immediately but add to the productive capacity of the economy. -> correct
