Answer / Ankit Agarwal
In Perl, single quotes (`''`) preserve all whitespace and special characters as-is, while double quotes (`""`) interpret variables and some special characters. For example:
```perl
my $single = 'Hello, World!'; # A string with no interpretation
my $double = "Hello, World!"; # A string with interpreted variables
