Checking checkbox A, triggers checkbox A & B. But checking checkbox B should only trigger checkbox B in Vuetify

I have two checkboxes in Vuetify. I'm trying to write them in a way that if I check checkbox A, it automatically checks both checkbox A & B. But clicking on checkbox B triggers only checkbox B. What's the best way to do it? Here is my code:

<v-checkbox label="A" value="A" v-model="A"> </v-checkbox>

<v-checkbox label="B" value="B" v-model="B"></v-checkbox>
