Answer 1

Option B is correct because we use nt command in order to check if a file or directory is newer than the other.

Option C is incorrect because it will not display the newer file.

Option D is incorrect because newer it is used to find file within a specified time

Option A is incort because using this command we can check if a file is readible or writable.

Option B is incorrect because because it is not used to check if a file is readible

Option C is correct because using this command we if we read a file and is not equal to the text file.
