You are developing an application. The application includes a method named ReadFile that reads data from a file. The ReadFile() method must meet the following requirements: ✑ It must not make changes to the data file. ✑ It must allow other processes to access the data file. ✑ It must not throw an exception if the application attempts to open a data file that does not exist. You need to implement the ReadFile() method. Which code segment should you use?

A. var fs = File.Open(Filename, FileMode.OpenOrCreate, FileAccess.Read,FileShare.ReadWrite);
B. var fs = File.Open(Filename, FileMode.Open, FileAccess.Read,FileShare.ReadWrite);
C. var fs = File.Open(Filename, FileMode.OpenOrCreate, FileAccess.Read,FileShare.Write);
D. var fs = File.ReadAllLines(Filename);
E. var fs = File.ReadAllBytes(Filename);
