Select the correct answerWhat will be the output of the following Python code?def ct(x, y, z): global a x = 5 y = 6 z = 7 a = 8 print(x,y,z,a)x,y,z,a = 15,16,17,18ct(1,3,9)Options5 6 7 81 5 9 1815 16 17 181 5 9 8

The correct answer is 5 6 7 8.

Here's the step by step explanation:

1. The function ct(x, y, z) is defined to take three arguments. Inside the function, the global variable 'a' is declared. Then, x, y, z, and a are assigned the values 5, 6, 7, and 8 respectively.

2. The print statement inside the function prints the values of x, y, z, and a which are 5, 6, 7, and 8 respectively.

3. Outside the function, x, y, z, and a are assigned the values 15, 16, 17, and 18 respectively. However, these assignments do not affect the print statement inside the function because the function has its own local variables x, y, and z. The global variable 'a' inside the function shadows the global variable 'a' outside the function.

4. When the function ct(1,3,9) is called, it ignores the values 1, 3, and 9 passed as arguments because x, y, and z are immediately assigned new values inside the function. Therefore, the print statement still prints 5, 6, 7, and 8.
