Answer:
The answer is "Option ".
Explanation:
The SOA stands for "Service-Oriented Architecture", which is primarily known as a service set and these services enable you to communicate with each other. In the communication, it may require simple data to transfer to two or more services, which can be organized by those operations, and other options were incorrect, that can be explained as follows:
- In option a, It is a business software, which is used to organized data, that's why it is wrong.
 - Option b and Option d both are wrong because the mashup process is used only on web services, which is not a part of SOA , that's why it is wrong.
 
 
        
                    
             
        
        
        
The pseudocode to find the sum of all integers that are multiples of 9, from 1 to 250.
totalSum = 0
for i from 1 to 250{
      if i is divided by 9 and remainder is 0{
            totalSum  = totalSum + i;
      }
}
print(totalSum)
in python language the code will be
totalSum = 0
for i in range(1,250):
     if i%9==0:
        totalSum += i
If you will run the program , the answer would be 3402.
