Why do we always pick the vertex with minimum weight in each iteration in prims algorithm as we are updating all the vertex with it’s minimum weight?

I am really trying to understand since last 3 days someone please help me out

It is simply because Prim’s algorithm is a greedy algorithm and you have to make a MST.

But why do we choose with minimum weight
I mean is it ok if we remove that loop?

bc it is mst (minimum spanning tree). A tree with minimum weight

What I am saying is everytime we are updating the vertex with minimum

What do you want to select then
