Answer:
The correct answer is option D. To avoid getting inappropriate texts or emails.
Explanation:
With the advancement of technology, the majority of the world's population has access to the internet, and also to social networks.
Any stranger could enter your social networks, and if you had personal data such as e-mail or your phone number it could be dangerous, so you should avoid putting this type of information in an account that everyone has access to.
The most convenient thing is that you give your number and your e-mail to your friends and family, to ensure that you will not receive any inappropriate content.
