The correct answer is option 'D' - 1, 2, 3, and 4. In linear queues, all four of the mentioned operations are performed.

1. Testing a linear queue for underflow:
Underflow occurs when we try to dequeue (remove) an element from an empty queue. Before performing a dequeue operation, it is important to check if the queue is empty or not. If the queue is empty and we try to dequeue an element, it will result in underflow. Therefore, it is necessary to test a linear queue for underflow before performing a dequeue operation.

2. Enqueue operation:
Enqueue operation is used to insert (add) an element at the end of the linear queue. In this operation, a new element is added to the back of the queue, increasing its size by one. The enqueue operation is performed when there is available space in the queue and the element can be successfully added.

3. Dequeue operation:
Dequeue operation is used to remove an element from the front of the linear queue. In this operation, the element at the front of the queue is removed, and the remaining elements are shifted forward. The dequeue operation is performed when there is at least one element in the queue.

4. Testing a linear queue for overflow:
Overflow occurs when we try to enqueue (insert) an element into a full queue. Before performing an enqueue operation, it is important to check if the queue is already full or not. If the queue is full and we try to enqueue an element, it will result in overflow. Therefore, it is necessary to test a linear queue for overflow before performing an enqueue operation.

In summary, linear queues support all four operations - testing for underflow, enqueue, dequeue, and testing for overflow. These operations ensure the proper functioning and management of the linear queue data structure.
