What would be different behaviour and result on different values of page options and their combination in Sveltekit?

Question

Sveltekit provide 3 page options givent https://kit.svelte.dev/docs/page-options

1. prerender
2. csr
3. ssr

These are the possible cases

1. Taking one at a time
   e.g. where we are setting
   export const prerender = true;
   or
   export const prerender = true;
   or
   export const prerender = false;
   or
   export const csr = true;
   or
   export const csr = false;
   or
   export const ssr = true;
   or
   export const ssr = false;
2. Taking two at a time
   export const prerender = true; and export const csr = true;
   or
   export const prerender = true; and export const csr = false;
   or
   export const prerender = false; and export const csr = true;
   or
   export const prerender = false; and export const csr = false;
   or
   export const prerender = true; and export const ssr = true;
   or
   export const prerender = true; and export const ssr = false;
   or
   export const prerender = false; and export const ssr = true;
   or
   export const prerender = false; and export const ssr = false;
   ...
   ...
   So many more possibities of combination of value of ssr and csr
3. Taking three at time
   e.g. So many possiblites of combination of values of ssr, csr and prerender

Out of these so many possiblites some may be non-sensible but some would be sensible.

So what would be different behaviour and results on these various possibities?
