B. Constipation, abdominal pain, cramps, blood clots
C. Nasal congestion and discharge, cough, sorethroat, headache
D. High fever, weakness, stomach pain, loss of appetite and constipation

Explanation

To determine the group of symptoms indicative of pneumonia, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Pneumonia**:
- Pneumonia is an infection that inflames the air sacs in one or both lungs, which can fill with fluid or pus. It can be caused by bacteria, viruses, or fungi.

2. **Identify Common Causes**:
- The most common bacterial causes of pneumonia include **Streptococcus pneumoniae** and **Haemophilus influenzae**.

3. **Recognize Affected Areas**:
- The infection primarily affects the **alveoli**, the tiny air sacs in the lungs.

4. **List Typical Symptoms**:
- Symptoms of pneumonia often include:
- **Fever**: A common response to infection.
- **Chills**: Often accompany fever.
- **Cough**: Typically a productive cough, meaning it may produce phlegm or mucus.
- **Headache**: Can occur due to fever or systemic infection.

5. **Evaluate Given Options**:
- Compare the symptoms listed in the options with the typical symptoms of pneumonia.
- **Option A**: Fever, chills, cough, and headache – This matches the typical symptoms of pneumonia.
- **Option B**: Constipation, abdominal pain, cramps, and blood clots – These symptoms are indicative of amebiasis, not pneumonia.
- **Option C**: Congestion, cough, sore throat, and headache – These are more associated with common colds or viral infections, not specifically pneumonia.
- **Option D**: High fever, weakness, stomach pain, loss of appetite, and constipation – These symptoms suggest a gastrointestinal infection, not pneumonia.

6. **Conclude**:
- Based on the evaluation, the correct group of symptoms indicative of pneumonia is found in **Option A**: Fever, chills, cough, and headache.

### Final Answer:
The group of symptoms indicative of pneumonia is **Fever, chills, cough, and headache** (Option A).
