What is the purpose of a centre punch?

Explanation:
The main idea is that a centre punch is used to create a small indentation at the exact spot where a hole will be drilled. That dent gives the drill a precise starting point, so the bit doesn’t wander as it begins cutting. This helps ensure the hole goes exactly where you intend and stays centered. The other functions listed aren’t what a centre punch does: marking 90° angles is what a square or marking tool is for; measuring small lengths is done with a caliper or ruler; scribbling parallel lines is done with a mark gauge or straightedge. A centre punch isn’t used for those tasks.
