Its not necessary to evaluate it using each theory. US has adopted a realist or you can say neo-realist approach towards china and the Indo-pacific policy is just one of its offshoots. Its a classic case of Thucydides trap.

And i remember the css2020 IR-II paper asked this while mentioning Chinese economic progress. That allowed us to mention critical theories as well.

To sum up, you dont need to utilize each theory. Just the one you think is pertinent and build your case from there with IR Jargon and references.
