Complete step by step answer:
In this question we have to convert this given number from the international system to Indian number system.
First, we should draw a table of conversion from international number system to Indian number system.

As, we can see here that One thousand in Indian system is equal to one thousand in the international system.
Similarly, ten thousand is equal to ten thousand in international system, one lakh is equal to hundred thousand in international system, ten lakhs are equal to one million in international system, one crore is equal to ten million in international system and ten crores is equal to hundred million in international system.
So, 10 million is equal to 1 crore.
And we have been given 35,987,123 that is, thirty-five million nine hundred eighty-seven thousand one hundred and twenty-three. Which in Indian number system will be, three crores fifty-nine lakh eighty-seven thousand one hundred twenty-three. Which can be written as 3,59,87,123.
Hence, Option B. 3,59,87,123 is correct.

Note: Whenever we face such types of problems the key point to remember is that we need to have a good grasp over the conversion of Indian number system to international number system, we can also make a table, like drawn above which can help us in simplification and getting on the right track to reach the answer.
