Answer:
An object’s position changes if there is a change in reference point.
Thus Option A is the right answer
Explanation:
When a place and object is used to compare whether an object is in motion or not, this place or object is considered as reference point. We call an object is moving when the distance between that object and another object changes.

Microorganisms of every description revel in the warm, damp, nutritive climate of your body. however, your body has four lines of defense to keep it from being overwhelmed.
Microorganism
A microorganism, often known as a microbe, is a microscopic-sized organism that can be either a single cell or a group of cells.
Ancient texts, including those found in India's Jain scriptures from the sixth century BC, express suspicions about the potential existence of unseen microscopic life. When Anton van Leeuwenhoek first observed microorganisms under a microscope in the 1670s, the scientific study of them had just begun. Louis Pasteur's discovery that bacteria were to blame for food rotting in the 1850s disproved the notion of spontaneous creation. Robert Koch made the discovery that bacteria were to blame for tuberculosis, cholera, diphtheria, and anthrax in the 1880s.
