Dijkstra's algorithm finds the shortest path:

A. from one specified vertex to all the other vertices
B. from one specified vertex to another specified vertex
C. from all vertices to all other vertices that can be reached along one edge
D. from all vertices to all other vertices that can be reached along multiple edges

A. from one specified vertex to all the other vertices

Explanation:

Dijkstra's algorithm finds the shortest path from one specified vertex to all the other vertices

A. from one specified vertex to all the other vertices

Explanation:

Dijkstra's algorithm allows us to find the all the vertices from a chosen vertex. It is used to calculate the shortest path between points. Network routing protocols is a good example of this. While you are surfing on the internet, the content that will be shown to you comes from a server. The logic behind that follows this algorithm. Depending on your location, the content is provided to you from the closest server. To do that, all the servers that are close to you are considered and the one that has the shortest distance is selected.

i've had the same problem. i generally just ignore it, as a ton of these "verified answers" are completely wrong.
