Answer:
<u>Proportion </u>is the aspect in design theory that describe the relationship of one object to another object in size. 
Explanation:
Proportion is an important aspect in design theory in terms of size. It refers to the relationship between object of the design in terms of size. The relation between size of different object in design theory can describe as, if the size of one object increases or decreases, it may leads to change in size of other object. It is called proportion.
If the size of one object increase with the size of other object, the relation is called direct proportion. If the size of one object decrease with the increase in size of other object is called inverse proportion.
 
        
             
        
        
        
Answer:
#include <iostream>
using namespace std;
int main()
{
    string str;
    cout<<"Enter the string: ";
    cin>>str;
    for(int i=0;str[i]!='\0';i++){
        if(str[i]=='e'){
            str[i]='x';
        }
    }
    cout<<"the string is: "<<str<<endl;
   return 0;
}
Explanation:
First, include the library iostream for using the input/output instructions.
Create the main function and declare the variables.
Then, use the cout instruction and print the message on the screen.
cin store the string enter by the user into a variable.
After that, take a for loop and if-else statement for checking the condition if the string contains the 'e', then change that alphabet to 'x'.
This process continues until the string not empty.
Finally, print the updated string.
 
        
             
        
        
        
Answer:
The answer is C) SQL Injection
Explanation:
Cross-Site Scripting (XSS) attacks are a type attacks that occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user. 
Cross-Site Request Forgery (CSRF) is a type of attacks specifically target state-changing requests, not theft of data, since the attacker has no way to see the response to the forged request. 
SQL Injection is a type of cyber security attack where an attacker inputs a malicious input into an SQL statement., and the SQL server reads it as programming code.
Address Resolution Protocol poisoning (ARP poisoning) is a form of attack in which an attacker changes the Media Access Control (MAC) address and attacks an Ethernet LAN by changing the target computer's ARP cache with a forged ARP request and reply packets. 
From the above brief definition; it is seen that the answer is C) SQL Injection.
