• A. $987,643$
• B. $4,000,000$
• C. $9,876,430$
• D. $9,999,999$

Answer 1

The correct option is C $9,876,430$

A larger digit at a larger place gives a larger number.
The number is formed in the following way:

First, we place the largest digit (among given digits) '$9$' at M

Then, we place the second largest digit (among given digits) '$8$' at HTh .

Similarly, we place all the digits in descending order to obtain the number.

$\therefore$ The number formed is $9,876,430$ .
