To determine which methods can be included under natural methods of birth control, we can analyze the various options available. Here’s a step-by-step breakdown of the natural methods of birth control:

### Step 1: Understand Natural Methods of Birth Control
Natural methods of birth control are those that do not involve any chemical or physical barriers. They rely on understanding and tracking the natural reproductive cycle.

### Step 2: Identify the Methods
1. **Rhythm Method (Calendar Method)**:
- This method involves tracking the menstrual cycle to predict ovulation.
- Couples avoid sexual intercourse during the fertile period (around ovulation) to prevent pregnancy.

2. **Coitus Interruptus (Withdrawal Method)**:
- In this method, the male partner withdraws the penis from the vagina before ejaculation.
- This is intended to prevent sperm from entering the female reproductive tract.

3. **Lactation Amenorrhea**:
- This method refers to the natural infertility that occurs when a woman is breastfeeding.
- During breastfeeding, the production of eggs is suppressed, leading to a lack of menstrual cycles for up to six months postpartum.

### Step 3: Conclusion
All three methods mentioned above are recognized as natural methods of birth control. Therefore, if the question provides these options, the correct answer would be that all of them can be included under natural methods of birth control.

### Final Answer
