Which of the following is NOT a common fishing tool used in rotary drilling?

Explanation:
In rotary drilling, a fishing tool must grab, hold, or attract the stuck object so it can be retrieved. An overshot slides around the fish and uses slips to grip it, allowing the toolstring to pull the fish out. A spear is designed to seize the end or body of the fish so it can be pulled free. A fishing magnet relies on magnetic attraction to recover ferrous metals without needing to physically clamp onto the item. A hydraulic jar, however, is used to deliver a sharp downhole impact to help free a stuck string or tool, not to capture or retrieve a fish. Because of this purpose, it isn’t a common fishing tool.
