Step 1: Understanding the Concept:
The Seventh Schedule of the Indian Constitution divides the legislative powers between the Union and the States into three lists: the Union List, the State List, and the Concurrent List. The question asks to identify subjects from the State List.
Step 2: Detailed Explanation:
The State List contains subjects on which only the State Legislatures can make laws. Let's examine the options:
\[\begin{array}{rl} \bullet & \text{Agriculture (Entry 14) is a key subject under the State List.} \\ \bullet & \text{Police and Public Order (Entries 1 and 2) are exclusive domains of the state government.} \\ \bullet & \text{Water, including Irrigation and canals (Entry 17), is also a State List subject.} \\ \end{array}\]
Since Agriculture, Police, and Irrigation are all subjects placed in the State List, the correct answer is "All of these".
Step 3: Final Answer:
All of the given subjects - Agriculture, Police, and Irrigation - are in the State List.
