Answer» Right ANSWER is (a) Prim’s algorithm initialises with a VERTEX The explanation is: Steps in Prim’s algorithm: (I) Select any vertex of GIVEN graph and add it to MST (II) Add the edge of minimum WEIGHT from a vertex not in MST to the vertex in MST; (III) It MST is complete the stop, otherwise go to step (II).
