So OPTION C is correct.

Yes, right @Brinda.

Yes, I agree the correct Answer is 'C'.

The correct answer: ls | wc-l

A. ls | wc --> Display the lines, words, and characters.

B. ls-l | wc -l--> Display total lines including one extra count since ls -l will give you another line with (total 0).

C. ls | wc -w--> Display all files and provide word count, but what will happen if a file name contains space, will it still give count as 2 or will it give the count as 3.

$ls
Test file
Test
$ls | wc -w

D. ls | ws -c --> Will give the character count of the list of files.

E. None of the above --> According to me this should be the answer.

Any thoughts will be much appreciated.

B is the correct answer.

Because, -w for word count and -c for character count.

ls -l option will give one extra count then the number of files.

ls -l | wc -l is correct option.

As it will give number of files stored in directory.

Incorrect option as it should be ls-l | wc-l

And to view hidden files as well it should be ls-la | wc-l
