javascript - Is it possible to pass a component as props and use it in a child Component in Vue?

In a Vue 2.0 app, let's say we have components A, B and C.

A declares, registers and uses B

Is it possible to pass C from A to B?

Something like this:

<template>
  <div class="A">
    <B :child_component="C" />
  </div>
</template>

And use C in B somehow.

<template>
  <div class="B">
    <C>Something else</C>
  </div>
</template>

The motivation: I want to create a generic component B that is used in A but receives from A its child C. Actually A will use B several times passing different 'C's to it.

If this approach is not correct, what is the proper way of doing it in Vue?

Answering @Saurabh

Instead of passing as props, I tried the suggestion inside B.

<!-- this is where I Call the dynamic component in B -->

<component :is="child_component"></component>

//this is what I did in B js
components: {
 equip: Equipment
}, 
data () {
 return {
   child_component: 'equip',
   _list: []
 }
}

Basically I'm trying to render Equipment, but the dynamic way

I get 3 errors in console and a blank page

[Vue warn]: Error when rendering component at /home/victor/projetos/tokaai/public/src/components/EquipmentFormItem.vue:

Uncaught TypeError: Cannot read property 'name' of undefined

TypeError: Cannot read property 'setAttribute' of undefined

Apparently I'm doing something wrong

Summing up:

<!-- Component A -->
<template>
  <div class="A">
    <B>
      <component :is="child_component"></component>
    </B>
  </div>
</template>

<script>
import B from './B.vue';
import Equipment from './Equipment.vue';

export default {
  name: 'A',
  components: { B, Equipment },
  data() {
    return { child_component: 'equipment' };
  }
};
</script>

<!-- Component B -->
<template>
  <div class="B">
    <h1>Some content</h1>
    <slot></slot> <!-- Component C will appear here -->
  </div>
</template>
