The level of consciousness of a child who recognizes his mother and wants to go to her is ________.

When a child recognizes their mother and expresses a desire to go to her, this indicates a high level of awareness and responsiveness to their surroundings. This behavior demonstrates that the child is able to process information and understand their emotional and physical environment. The term "alert" specifically refers to a state of wakefulness and awareness, where the individual can interact with others, respond appropriately to stimuli, and demonstrate recognition of familiar people and situations.

In this context, the other terms do not fit the scenario. "Unresponsive" would imply a complete lack of awareness or interaction, which does not describe the child's behavior. "Confused" suggests a state of disorientation, where the individual cannot properly understand or engage with their surroundings, which is also not the case here. "Drowsy" indicates a level of lethargy or sleepiness, where the individual may be conscious but not fully engaged, again contrasting with the child’s ability to recognize and desire to approach their mother. Thus, the child's recognition and intention to engage clearly demonstrate an alert state of consciousness.
