Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Define the variable only in the leaf module and refer to root by index.
Why it's wrong here
This is not a valid way to reference variables.
- ✓
You must define the variable in the intermediate module and pass it to the leaf module.
Why this is correct
Explicit declaration and assignment are required at every level of the hierarchy.
- ✗
You can use the 'global_vars' block in the root.
Why it's wrong here
There is no 'global_vars' block.
- ✗
The intermediate module automatically inherits all root variables.
Why it's wrong here
Variables must be explicitly passed down the module chain.
