In Python, modules are files that contain definitions and statements that can be reused in other programs. For example, the math module contains various mathematical functions and constants. To use a module, we need to import it using the import statement.
There are different ways to import a module or a specific function from a module in Python. Let’s look at the options and see why they are correct or incorrect:

Option a is incorrect because it is not a valid syntax for importing a function from a module. We cannot use the dot (.) operator after the import keyword. This will cause a syntax error. If we want to import the entire math module, we can use import math without the dot.
Option b is correct because it is a valid syntax for importing a specific function from a module. We can use the from keyword followed by the module name , then the import keyword followed by the function name. This will allow us to use the function without prefixing it with the module name. For example, we can use sqrt(4) instead of math.sqrt(4) .
Option c is incorrect because it is not a valid syntax for importing a function from a module. We cannot use the from keyword after the import keyword. This will cause a syntax error. The correct order is from <module> import <function>.
Option d is incorrect because it is not a valid syntax for importing a function from a module. We cannot use the function name as the source and the module name as the destination. This will cause an import error. The correct order is from <module> import <function>.

So, the correct answer is b. from math import sqrt.
