d. Selective mutism

The correct answer is d. Selective mutism.

Selective mutism is a relatively rare childhood anxiety disorder characterized by a persistent failure to speak in specific social situations, such as school or public events, despite being able to speak in other situations. Children with selective mutism may display normal language skills and comprehension but become unable to speak in certain social situations due to extreme shyness, fear, or anxiety.
