A Correct answer
Explanation

Perl's shift() function removes and returns the first element from an array. This is the standard way to access the first item, making option A correct. Functions like start, left$, and right$ don't exist in Perl. unshift adds to the beginning, pop/shift remove from ends, but shift is specifically for the first element.
