[amp_mcq option1=”A goal state is unreachable from any state” option2=”A goal state is denied access” option3=”A goal state is reachable from every state” option4=”None of the mentioned” correct=”option1″]
The correct answer is: A goal state is reachable from every state.
A goal state is a state in which the problem is solved. A state is said to be safely explored if it is reachable from a goal state and there is no path from it to a state that is not reachable from a goal state.
Option A is incorrect because a goal state can be reachable from some states but not from others.
Option B is incorrect because a goal state can be reachable from every state.
Option C is incorrect because a goal state can be reachable from some states but not from others.
Option D is incorrect because the answer is A.
