To answer this question, you need to understand the purpose and characteristics of these functions.
Option A) Safe APIs - This option is incorrect because some of the functions mentioned, such as gets(), are considered unsafe and can lead to buffer overflow vulnerabilities.
Option B) Banned APIs - This option is correct because some of the functions mentioned, such as gets(), are considered unsafe and have been banned in modern programming practices due to security concerns.
Option C) String APIs - This option is incorrect because while some of the functions mentioned, such as strcpy(), strcat(), and strncpy(), are related to manipulating strings, not all of them fall into this category.
Option D) CAPIs - This option is incorrect because the term "CAPIs" is not commonly used to refer to these functions.
