To determine the time complexity of inserting a node based on a key in a priority queue, we need to consider the underlying data structure used to implement the priority queue.

One common implementation of a priority queue is a binary heap. In a binary heap, the insertion operation involves adding the new node at the bottom of the heap and then "bubbling up" the node to its correct position based on its priority.

The "bubbling up" process requires comparing the priority of the new node with its parent node and swapping them if necessary. This process continues until the new node reaches its correct position in the heap.

In a binary heap, the height of the tree is logarithmic to the number of nodes, which means that the number of comparisons required during the insertion process is proportional to the height of the tree.

Therefore, the time complexity of inserting a node based on a key in a priority queue implemented using a binary heap is O(logn), where n is the number of nodes in the priority queue.

So, the correct answer is b) O(logn).
