Maslow's theory is based on the following assumptions:

(A) People's behaviour is based on their needs. Satisfaction of such needs influences their behavior.

(B) People's needs are in hierarchical order, starting from basic needs to other higher level needs.

(C) A satisfied need can no longer motivate a person; only the next higher level need can motivate him.

(D) A person moves to the next higher level of the hierarchy only when the lower need is satisfied.

Choose the correct answer from the options given below:

Option 1 -> (A), (B) and (D) only - This excludes statement (C) about satisfied needs no longer motivating, which is a key principle of Maslow's theory, making this incomplete.

Option 2 -> (A), (B) and (C) only - This excludes statement (D) about progression through hierarchy levels, which is fundamental to Maslow's hierarchical concept, making this incomplete.

Option 3 -> (A), (B), (C) and (D) - This includes all four statements which are all fundamental assumptions of Maslow's Hierarchy of Needs theory.

Option 4 -> (B), (C) and (D) only - This excludes statement (A) about behavior being based on needs, which is the foundational premise of Maslow's motivation theory, making this incomplete.

Hence, Option 3: (A), (B), (C) and (D) -> All four statements accurately represent Maslow's core assumptions: (A) needs drive behavior, (B) needs are hierarchically ordered from basic to higher-level, (C) satisfied needs cease to motivate and are replaced by next-level needs, and (D) progression occurs only after lower needs are satisfied. These collectively form the complete theoretical framework of Maslow's Hierarchy of Needs. -> correct
