The extreme fear that Raunak is experiencing is related to specific objects (lizards and snakes), and it is an intense, uncontrollable fear that interferes with his daily functioning. This is characteristic of Anxiety disorders, specifically Phobias, which are part of anxiety disorders. Phobias are marked by excessive and persistent fear of certain situations or objects. In Raunak's case, his fear of reptiles is beyond what is considered typical and leads to physical symptoms such as sweating, heart palpitations, and fainting.
- Somatic symptoms disorder involves excessive focus on physical symptoms like pain or fatigue, which does not fit Raunak's case.
- Obsessive compulsive disorder involves persistent thoughts (obsessions) and repetitive behaviors (compulsions), which does not describe Raunak's situation.
- Dissociative disorder involves disruptions in memory, identity, or perception, which is not relevant here.
Thus, the correct answer is Anxiety disorder.
