Hint: The number of types of cell in the human body is over 200. Each type of cell is given its own job which is done by them either solely or by forming a tissue. Organs are formed by the collection of tissue where our organs are like a factory with every type of cell having a specific job to do.

Complete answer:
-Each and every type of cell has a distinct shape and size. In our body, some cells are closely packed whereas some are apart. Cells die at a constant rate and new ones are born too. The number of cells in a body will depend upon factors like age, height, weight, and surrounding of the person. Cells are a very essential part of our body without which our body won’t work efficiently. It is not possible to name all the types of cells but here are a few of them, red blood cells,white blood cells, skin cells, neurons, fat cells, sex cells,and many more. Red blood cells cover the most percentage of the cells. Red blood cells cover approximately eighty percent of the cells. As they are the most abundant of all the cells, an average human body makes around 2-3 million red blood cells every second.
Hence, option C: 260 is correct.

Note: Recent study shows that there are over thirty trillion cells on an average human body. As red blood cells are the most abundant of all the cells, an average human body makes around 2-3 million red blood cells every second.
