According to the material, what is the earliest age at which self-awareness is demonstrated in infancy?

• A. 3 months
• B. 9 months
• C. 12 months
• D. 5 months

Answer: (D)

The idea being tested is when infants first show signs that they understand themselves as an active agent in the world. By about five months, babies begin to initiate actions that affect their surroundings (for example, kicking a mobile to make it move), showing they recognize their own actions can cause changes. This reflects an early sense of self as separate from the world and as capable of influencing it. Later, more advanced self-recognition, like identifying themselves in a mirror, develops later, but five months is cited as the earliest demonstrated self-awareness in the material.
