An increase in the marginal propensity to consume …
[1] decreases the value of the multiplier
[2] does not affect the multiplier.
[3] increases the value of the multiplier.
[4] will not occur because the marginal propensity to consume is set by government.
As multiplier formula is m = 1/(1 - mpc), then an increase in the marginal propensity to consume increases the value of the multiplier.
So, the correct answer is [3].
