C

Explanation:
Maslow’s hierarchy of needs is structured in ascending order: physiological, safety, social, ego (esteem), and self-actualization. Option C correctly lists safety, social, ego, and self-actualization, representing the hierarchy from lower to higher needs (assuming physiological needs are implied as the base). Option A is incorrect as it starts with self-actualization, the highest need, and reverses the order. Option B incorrectly places ego before social and skips safety. Option D misorders the sequence by starting with ego and placing safety after it. Option C aligns with Maslow’s model, correctly sequencing the needs.
