Options

A. heterodont, thecodont, diphyodont
B. thecodont, heterodont,dihyodont
C. diphyodont,thecodont,heterodont
D. heterodont,diphyodont,thecodont

Answer

To solve the question regarding the types of teeth in mammals, we will analyze each condition mentioned in the question step by step.

### Step-by-Step Solution:

1. **Different Types of Teeth**:
- In mammals, teeth are categorized into different types based on their shape and function. The main types include incisors (for cutting), canines (for tearing), premolars, and molars (for grinding). This variation in tooth types is known as **heterodont**.

2. **Embedded in Socket**:
- Mammalian teeth are not simply attached to the jaw; instead, they are embedded in cup-like sockets called alveoli within the jawbone. This arrangement is referred to as **thecodont**.

3. **Two Sets of Teeth**:
- Mammals typically have two sets of teeth during their lifetime: the first set is the milk teeth (deciduous teeth), which are replaced by the permanent teeth (adult teeth). This condition is known as **diphyodont**.

### Final Answer:
The conditions described in the question are referred to as:
- (a) Heterodont (different types of teeth)
- (b) Thecodont (teeth embedded in sockets)
- (c) Diphyodont (two sets of teeth)

Thus, the answer is: **Heterodont, Thecodont, Diphyodont**.
