C. Identifying the offense, from religion to homosexuality.

Explanation:

Around the 1930s, prisoners remanded in the Nazi concentration camp were mainly identified by badges (colored triangles with letter inscriptions).

The main purpose of colored badges or triangles on camp uniforms is for identifying the offense, from religion to homosexuality. Thus, these colored badges were sewn to the prisoner's jacket and trouser and are typically used to identify reasons for the conviction of each prisoners in the German-occupied countries or territories.

Basically, the color and shape of the badge depicts or denotes the type of offence being committed by the prisoner and consequently, helps the prison guards to assign tasks to them.

Hence, in the Nazi concentration camp, a pink triangle is sewn on the uniform of prisoners that have committed offences related to sex such as homosexuality and a purple triangle for an offense relating to religion.
