Know the truth, Shed the light on the truth, Make the truth clear


I’m wondering which phrase could best fit in the following sentence?

A-Isn’t this the money you filed suit against your uncle for? And now you got what you wanted.

B-I filed the lawsuit just because I wanted to…

1- Know, find the truth
2- Shed, throw, cast the light on the truth
3- Make the truth clear

Thank you.

I think know the truth, find the truth, discover the truth, shed light on the truth, throw light on the truth, cast light on the truth (no “the” before light) and make the truth clear are all fine.
