Final answer:
In hockey, spearing is the act of poking with the point or butt end of the stick and is penalized as a dangerous play, distinct from hooking, clipping, and icing which are different rules or infractions in the game. Hence, the third option is correct.
Step-by-step explanation:
In hockey, spearing is defined as poking with the point or butt end of the stick. This action can be dangerous and is considered a penalty within the game. Unlike hooking, which involves using the stick to impede a player's movement, or clipping, which is a low body check, spearing specifically involves the stick making a jabbing motion. Icing, on the other hand, is a rule related to the position of the puck and players on the ice and is unrelated to stick infractions.
Therefore, among the given options, the correct answer is the third option: spearing.
