Concept:Mental health refers to the overall well-being of a person's mind, including how one thinks, feels, and behaves.
Explanation:Mental health is not merely the absence of mental illness.
It includes three main components.
First, cognitive well-being means the ability to think clearly, make decisions, and solve problems.
Second, behavioural well-being means the ability to engage in positive actions, maintain relationships, and fulfil responsibilities.
Third, emotional well-being means the ability to manage and express emotions in a healthy and balanced manner.
Together, these three components define mental health as cognitive, behavioural, and emotional well-being.
Options A, C, and D are incomplete because they omit one or more of these core aspects.
Therefore, the most accurate definition is given in option B.
Answer:B. It is cognitive, behavioural and emotional well being.
