Mario Knows That, Over the Long Run, It Is in His

Mario knows that, over the long run, it is in his best interest to save at least 10% of his paycheck for retirement. However, each time he receives his weekly paycheck of $1,000, he ends up spending it all and not depositing any to a retirement account. Mario has resolved to contact his employer's human resources department to set up a 401(k) work-sponsored retirement account where the 10% would be deducted automatically from his paycheck before it is issued to him each week. It is apparent from this information that Mario realized that:

B) his intertemporal decisions are consistent and he had to take action to make them inconsistent.
C) it is better for him to handle sending money to a retirement account than to rely on his employer to send the money to a retirement account on his behalf.
D) he should not be saving for retirement after all because his short-run preferences to spend his entire paycheck are perfectly indicative of his long-run preferences.
E) he should not worry about the future anymore because it will take care of itself.
