Public goods are non-excludable and non-rivalrous

Steps:

• Recall definition: Public goods provide benefits that are non-excludable (cannot prevent non-payers from using) and non-rivalrous (one person's use does not diminish another's).
• Evaluate education: It is typically provided through schools with fees or taxes, but access can be restricted, and seats/resources are limited.
• Evaluate other options: Flood control, national defense, and street lighting benefit entire populations without exclusion or rivalry.
• Identify mismatch: Education fails both criteria, unlike the others.

Why A is correct:

• Education is excludable (non-payers can be denied enrollment) and rivalrous (limited classroom spots reduce availability), per economic classification of goods.

Why the others are wrong:

• B: Flood control is non-excludable (protects all in area) and non-rivalrous (protection for one does not reduce for others).
• C: National defense is non-excludable (protects all citizens) and non-rivalrous (security for one does not diminish for others).
• D: Street lighting is non-excludable (illuminates public spaces) and non-rivalrous (light use by one does not affect others).

Final answer: A
