You create a Windows application by using the .NET Framework 3.5. The application is named APP1. APP1 has the following specifications:

* It merges information from text files.
* It reads each text file as a string.
* It runs on a server computer named Server1.

Another application named APP2 also runs on Server1. You discover that when a function is used to merge the text files, APP1
consumes additional memory. This additional memory consumption affects the operations of APP2.

You need to modify the design of APP1 to ensure minimum effect on APP2. What should you do?

A.
Use the + operator for the merge process.

B.
Use the StringBuilder.Append method for the merge process.

C.
Write a code segment to perform the merge process on a new thread.

D.
Write a code segment in a separate project to perform the merge process. Configure the project to start the merge operation as a new process.
