The Correct Option is C

Solution and Explanation

Concept: Investment multiplier shows how much national income changes due to a change in investment. \[ k = \frac{1}{1-MPC} \]

Step 1:
Substituting the value of MPC.
Given: \[ MPC = 0.8 \] \[ k = \frac{1}{1-0.8} \]

Step 2:
Simplifying the expression.
\[ k = \frac{1}{0.2} \] \[ k = 5 \]

Step 3:
Final conclusion.
Therefore: \[ \boxed{\text{(C) }5} \]
