Final Answer :
C
Explanation :
The Marginal Propensity to Consume (MPC) is calculated as the change in consumption divided by the change in income. From the table, when income increases by $100 (from $0 to $100, for example), consumption increases by $80 (from $140 to $220). Therefore, MPC = $80 / $100 = 0.8.
