[amp_mcq option1=”Change in the desired literals” option2=”Not any change in the literals” option3=”No change in goal state” option4=”None of the mentioned” correct=”option2″]
The correct answer is: B. Not any change in the literals.
A literal is a propositional atom or its negation. In state-space search, a state is a set of literals. A state is consistent if it satisfies all of the goal literals and does not satisfy any of the negative goal literals.
Option A is incorrect because it states that the desired literals can change. However, the desired literals are fixed at the beginning of the search process and do not change.
Option C is incorrect because it states that the goal state can change. However, the goal state is also fixed at the beginning of the search process and does not change.
Option D is incorrect because it states that none of the mentioned options are correct. However, option B is the correct answer.
