Final answer:
The number 123,080,603 is correctly written in word form as 'One hundred twenty-three million eighty thousand six hundred three', which corresponds to Option A.
Step-by-step explanation:
The correct number name for 123,080,603 is Option A: One hundred twenty-three million eighty thousand six hundred three. When expressing numbers in words, each group of three digits from right to left represents a specific place value - hundreds, thousands, millions, and so on. The first group is the hundreds (up to 999), followed by thousands (up to 999,999), millions, and higher. It is important to state 'hundred' and 'thousand' when applicable, as they represent the corresponding place values. In this case, 'hundred' is stated to represent the hundreds place in the million group, and 'thousand' to represent the thousand place between the million and the hundred. Hence, zeros are not explicitly mentioned when they occur in place values that are not accompanied by other non-zero digits.
