The atomic sections with choice are P₄ and P₅.
The atomic sections with choice are (1) P₄ and P₅, and (2) P₃ and P₆.
The atomic sections with choice are (1) P₄ and P₅, and (2) P₁ and P₆.

Answer :-

9. What do the atomic sections P₁ and P₇ take care of in the given code?

These atomic sections take care of generating the header and body tags of the HTML file that will be sent to the client browser.
