Hint: In this question, we are given a numeral and we need to convert it into words. For this, we will first split the given numeral into hundreds, thousands, and millions. Using this we will be able to write the number into words easily.

Complete step by step answer:
Here we are given the number 123, 080, 603. We have to write it in words. According to the International system of numeration, we have placed as ones, tens, hundreds, thousands, ten thousand, hundred thousand, million, ten million, hundred million and so on. The value of one hundred is 100, the value of one thousand is 1000, and the value of one million is 1,000,000.
Now let us split the given numeral into million, hundreds, thousands, we get.
$123000000+080000+600+3 $.
Here 3 can be written as three, 600 can be written as six hundred (6 is at hundreds of places), 80000 can be written as eighty thousand (8 is at ten thousand places and there is no digit at hundred thousand places), 123,000,000 can be written as one hundred twenty-three million (1 is at hundred million places, 2 is at ten million places and 3 is at million places).
Combining all these we get,
One hundred twenty-three million eighty thousand six hundred three. Thus this is our required answer.
Hence option C is the correct answer.

Note:
Students should take care of zeroes in these conversions. They should know the places for the international system of numeration as well as the Indian system of numeration. Students can solve this sum using a place value chart. Placing all the numerals from right to left in the chart will give us an idea of writing them in word form.
