Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In ls -l output, the first character indicates file type: 'd' for directory, '-' for regular file. grep "^d" filters lines starting with 'd', showing only directories. Option A's ls -d lists directory entries but doesn't filter contents by type; Option B uses a variable pattern that won't match the directory marker.
