Which of the following accurately describes how a block-scoped variable behaves outside of its block?
- It is accessible outside the block.
- It is undefined outside the block.
- It retains its value outside the block.
- It causes a syntax error if accessed outside the block.
Block-scoped variables in JavaScript are not accessible outside of their block. They have limited scope to the block they are declared in, and attempting to access them outside of that block results in an "undefined" value. This behavior helps prevent unintended variable conflicts and maintains better code isolation.
