Age of consent is the legal age when a person can agree to sexual activity. Raising it protects young people from abuse and exploitation.
Step 2: Japan’s recent law change
Japan raised its national age of consent from 13 to 16 years, following concerns for better child protection and international alignment.
Step 3: Importance
This change aims to ensure young individuals’ rights and safety are respected.
Step 4: Other countries
Other countries listed did not recently make this change.
Thus, Option (B) Japan is correct.
