Final answer:
The three categories of mothers of incest victims are Category A, Category B, and Category C.
Step-by-step explanation:
In the context of Johnson's categorization, the three categories of mothers of incest victims are as follows:
- Category A: This category includes mothers who are completely unaware of the incestuous abuse happening to their child.
- Category B: This category consists of mothers who have some knowledge or suspicion of the abuse but fail to take appropriate action to protect their child.
- Category C: This category encompasses mothers who actively participate or encourage the incestuous abuse.
This categorization is used to understand the various ways in which mothers may respond or be involved in cases of incestuous abuse.
