Question: What is the difference between the declarations of COLOR and SIZE?

1. Since `COLOR` and `SIZE` are both immutable, they are identical internally
2. Both are immutable, but the use of the keyword const makes `COLOR` slower and less space efficient than `SIZE`
3. const makes `COLOR` faster, but not compatible with Java. Without const, `SIZE` is still compatible with Java
4. Both are immutable, but the use of the keyword const makes `COLOR` faster and more space efficient than `SIZE`

Answer: The correct answer of the above question is Option D:Both are immutable, but the use of the keyword const makes `COLOR` faster and more space efficient than `SIZE`
