A global variable is available everywhere in the code.

A quick look at the proposition helps set the stage for evaluating each option.
Option 1: True. In some programming contexts, a global variable is defined in a scope that places it at the top level, making it accessible from many or all parts of the program. This reflects the common definition of a global variable as one that has global scope and thus can be read or modified from anywhere in the code, barring any language-specific restrictions such as modules or namespaces.
Option 2: False. The statement that a global variable is not accessible everywhere is inaccurate in typical interpretations. While there are languages or systems that restrict visibility via modules, namespaces, or encapsulation mechanisms, the classical concept of a global variable is that it is available globally across the program. Saying it is not accessible everywhere would contradict that fundamental idea and would only be true in scenarios with strict scoping or intentional access controls, not as a general rule.
If you consider languages with module boundaries or object-oriented encapsulation, you might encounter cases where a variable appears to have limited visibility, but that still does not negate the standard definition of a global variable in many languages where its scope is program-wide. The contrast between global scope versus local scope is what often leads to confusion, so keeping in mind the general definition helps resolve this.
