Consider the following statements regarding STRIPS representation of a…

Final answer: 'A, C Only' — STRIPS is feature-centric and actions comprise preconditions and effects.

Statement: "STRIPS is a Feature-centric representation" — True. STRIPS represents world states as sets of ground predicates (features), so it is naturally feature-centric.

Statement: "The features describing state of the world are divided into Primitive and Derived" — False. Classical STRIPS does not include a built-in notion of derived predicates or axioms; derived predicates are part of later extensions to the basic formalism.

Statement: "The STRIPS representation of the action comprises of Precondition and Effect" — True. In STRIPS an action is specified by its preconditions and its effects, typically given as add and delete lists.

Statement: "STRIPS can directly define conditional effects" — False. Conditional effects (effects that occur only when some additional condition holds) are not part of the classical STRIPS language; they require extended languages such as ADL or conditional-effect extensions in PDDL.

Summary: Only the statements that STRIPS is feature-centric and that actions have preconditions and effects are correct. Therefore the correct choice is the one listing those two statements ('A, C Only').

• Key point: STRIPS uses predicates/features to describe states.

• Key point: Actions in STRIPS are given by preconditions and effects (add/delete lists).

• Note: Derived predicates and conditional effects appear in extensions, not in classical STRIPS.
