3 inches per year best represents the average rate at which infants grow in height during the first four years after birth. The correct option among all the options that are given in the question is the second option or option "b". The other choices given in the question seems quiet absurd. So by the method of elimination, one can say that option "b" is correct.
The correct answer is option b, that is, 3 inches per year.
Explanation:
Humans seem to develop at a specifically gradual rate unless and until one reaches puberty. The rate of growth could differ on the basis of the genetic composition and nutrition plan of the infants. For example, the Asian babies grow at a gradual rate with 2 to 2.5 inches in a year. The three inches in a year best illustrates the average rate at which the infants grow in height at the time of the initial four years post-birth.
A cell is the smallest unit of a living thing. Whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.
