I am

• A. $50,000,000,000$
• B. $50,000,000$
• C. $5,000,000$
• D. $5,000,000,000$

Answer 1

The correct option is D $5,000,000,000$

As the number is in billions but less than $10$ billions , it is a 10 digit number. Let's put 0 at the place of Ten Billions.

A billion is a 10 digit number and there is only one $5$. Therefore, Zero cannot come in billions place as it will have no meaning.

Thus, the right answer is $5$ at billions place followed by zeroes.
