  • A Y = C - I + (x +m0
  • B Y = C + I + (x + m)
  • C Y = C +I +(X - M)
  • D Y =C + I + (m - x)

The correct answer is C. Y = C +I +(X - M)

Since national income is the gross domestic product of a country plus all the wages, salaries of its citizens abroad minus earnings of foreign citizens residing in the said country;

National Income = C + I + X - M (exports - imports)
