Answer:
we have the number 0,1,2,3,5,7
Now the digit should be odd and hence last digit should be
filled with an odd number
⇒ Number of way to filled last number =4 (i.e. 1,3,5,7)
⇒ Number of way to filled third digit =6 (i.e. 0,1,2,3,5,7)
⇒ Number of way to filled second digit =6 (i.e. 0,1,2,3,5,7)
⇒ Number of way to filled first digit =5 (i.e.1,2,3,5,7)
⇒ Total 4digit number =4×6×6×5
=720
hence,
Opton D is correct answer.
