To express the population of China, which is 1,244,130,000, in scientific notation, we need to convert it to the format \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.
First, we can rewrite the number in a more manageable form:
1,244,130,000 can be expressed as \( 12.4413 \times 10^9 \) (because we moved the decimal point 9 places to the left).
In scientific notation, this is approximately \( 1.24 \times 10^{9} \).
However, since your options appear to focus on \( 1 \times 10^n \), we need to round \( 1.24 \) to the nearest acceptable value for simplicity, which gives us \( 1 \times 10^9 \).
Thus, the correct answer based on the choices provided is:
C: \( 1 \times 10^9 \).
