The correct Answer is:

**Step-by-Step Solution:** 1. **Identify the Location of the Cardiac Center**: The cardiac center is located in the brain, specifically in the hindbrain region. 2. **Understand the Structure of the Brain**: The brain is divided into three main parts: the forebrain, midbrain, and hindbrain. 3. **Focus on the Hindbrain**: The hindbrain consists of three parts: the cerebellum, pons, and medulla oblongata. 4. **Locate the Cardiac Center**: The cardiac center is specifically found in the medulla oblongata, which is responsible for controlling involuntary activities, including heart rate. 5. **Summarize the Function**: The cardiac center regulates the heart's functions, such as heart rate and rhythm, making it essential for maintaining homeostasis. 6. **Conclude the Answer**: Therefore, the cardiac center lies in the medulla oblongata of the hindbrain. **Final Answer**: The cardiac center lies in the medulla oblongata of the hindbrain. ---

The differential equation of family of circles whose centre lies on x-axis, is

`(d^(2)y)/(dx^(2))+((dy)/(dx))^(2)+1=0`

`y(d^(2)y)/(dx^(2))+((dy)/(dx))^(2)-1=0`

`y(d^(2)y)/(dx^(2))-((dy)/(dx))^(2)-1=0`

`y(d^(2)y)/(dx^(2))+((dy)/(dx))^(2)+1=0`
