Answer / Nushrat Naz
{"instance_variable": "Instance variables are variables that belong to an individual object. They are created with the @ symbol before their name (e.g., @instance_var).","global_variable": "Global variables are variables accessible from anywhere within a Ruby program and are created using the $ symbol before their name (e.g., $global_var).","class_variable": "Class variables are variables that belong to a class and are created with two at signs (@@) before their name (e.g., @@class_var)."
