Concept:The passage indicates that while data protection laws exist in some countries, their implementation is weak.
Explanation:The passage explicitly says "some countries have passed laws to protect user data."
It immediately adds that "implementation remains weak."
This directly means the laws are present but poorly enforced.
Option A (strong and global) is not stated.
Option B (strict in all countries) contradicts the passage.
Option D (unnecessary) is never suggested.
Answer:C – They exist but are poorly enforced.
