Please answer the question below.
What does Tom want to know?
How to define constants in his project
Tom is asking about the distinction between two concepts, not how to define constants.
Why he should use constants instead of variables
This isn't correct because Tom's question is about understanding the differences, not the reasons for using one over the other.
The difference between variables and constants
Which is better to use in his project: variables or constants
This option is misleading. Tom is looking for clarification on the differences, not advice on which is better to use.
