B Correct answer
Explanation

Perl programs need execute permission to run directly. The 755 octal notation means: owner can read, write, execute (7); group can read and execute (5); others can read and execute (5). This is the standard permission for executable scripts, while 666 only allows read/write with no execute capability.
