Question

At any node along a critical path

Answer 1

Explanation:

You can have more than one critical path in a project, so that several paths run concurrently. This can be the result of multiple dependencies between tasks, or separate sequences that run for the same duration. ... In fact, the activities on the critical path are not always the most important parts of the project.

Answer 2

Explanation:

In project management, a critical path is the sequence of project network activities which add up to the longest overall duration, regardless if that longest duration has float or not. This determines the shortest time possible to complete the project. There can be 'total float' (unused time) within the critical path.
