Option A: We start with vertex A:
As per working of Prim's algorithm, after (a,b) the selected edge would be (a,d).
Hence option A is false.
Option B: Here, we start with vertex C:
Now here first edge chosen is (c,e) which is of higher cost than (c,f), which is not possible.
Hence, option B is false.
Option C: Here, we start with vertex D.
The given sequence here is correct, you can check it manually.
Option D: Just like option B:
Here we start with vertex G, and select (g,h) before (g,i), where (g,h) is of higher cost and this is not possible.
