Declaring a variable in Python involves simply using the assignment operator to assign a value to a variable name. The syntax is straightforward: you write the variable name followed by the equals sign and then the value you want to store. For example, if you want to create a variable named "age" and assign it the value 30, it would look like this: `age = 30`.

This method is dynamic in Python, which means you do not need to specify the type of the variable beforehand as Python handles variable types dynamically at runtime. This is a defining feature of Python as opposed to some other programming languages that require type declarations.

The other options suggest alternative syntax that does not apply to Python, reflecting conventions from different programming languages. For instance, using 'let' or 'var' is common in JavaScript, while 'declare' is not standard syntax in Python at all. Therefore, understanding the correct method of variable declaration in Python is essential for writing effective scripts and programs in this language.
