Read the passage carefully and answer the question that follows.
The Human Side of Cybercrime
As more Indians bank, shop and study online, cybercrime has grown at an alarming pace. Most attacks do not rely on complex hacking; instead, criminals exploit human trust. A typical fraud begins with a message that appears to come from a bank or a delivery company, urging the victim to click a link or share a one-time password. Once the code is shared, money can vanish from an account within minutes. Experts say that awareness is the most effective defence. Simple habits, such as never sharing passwords, checking website addresses carefully and enabling two-factor authentication, can prevent a large share of these crimes. Victims are also advised to report fraud immediately on the national cybercrime helpline, because quick action increases the chance of freezing the stolen money. While police forces are setting up specialised cyber cells and forensic laboratories, officials admit that technology alone cannot stop fraud. Ultimately, a cautious and informed user remains the strongest wall against online crime.
