Answer:
A. Arbitrary code execution
Explanation:
A buffer-overrun, also known as buffer overflow occurs when a programmer makes an error during coding, which could make his system easily susceptible to attacks from a hacker. The root cause of this problem is an overflow of data in a buffer, and programs that are written in C and C+ + are more likely to be affected by this problem. When a buffer-overrun occurs, it would most likely lead to arbitrary code execution.
Arbitrary code execution is an uncontrolled and unrestricted coding by the attacker which alters the original coding. The attacker could input more information into the coding, which alters the original information and which would make the application porous and accessible by just anyone. It is important that programmers run regular tests on their programs, so as to detect any coding errors.
The input function reads a piece of data that has been entered at the keyboard and returns that piece of data, as a string, back to the program. This function is designed to accept data directly from the user, Similar function is the function raw_input() used in Python programming, which asks the user for a string of data (ended with a newline), and simply returns the string.
use an anchor tag(<a>This is an anchor tag</a>) and use the href attribute and set it's destination to the section element who's id or class is "sisters".
Example:
<a href="#Sisters">Click Here!</a>
then you can add this somewhere on the document.
<section id="Sisters">Hello World!</section>
