The correct answer is C. 3.
State-space search is a technique used to solve problems by exploring a set of possible states. The goal is to find a state that satisfies a given goal condition. The search algorithm starts at the initial state and then explores all possible successor states. If a successor state satisfies the goal condition, then the algorithm has found a solution. Otherwise, the algorithm continues to explore successor states until it finds a solution or until it determines that there is no solution.
The number of states available in state-space search depends on the problem being solved. For some problems, there may be only a few possible states. For other problems, there may be millions or even billions of possible states. The number of states also depends on the search algorithm being used. Some algorithms are more efficient than others and can explore a larger number of states in a shorter amount of time.
The following are the possible options for the question:
- A. 1: This option is incorrect because there are at least 3 states available in state-space search. The initial state, the goal state, and any intermediate states that are explored during the search.
- B. 2: This option is incorrect because there are at least 3 states available in state-space search. The initial state, the goal state, and any intermediate states that are explored during the search.
- C. 3: This option is correct because there are at least 3 states available in state-space search. The initial state, the goal state, and any intermediate states that are explored during the search.
- D. 4: This option is incorrect because there are at least 3 states available in state-space search. The initial state, the goal state, and any intermediate states that are explored during the search.
