Answer 1

The correct option is B $1,05,689$

$\Rightarrow$ The given numbers are $9,6,0,5,8,1$

$\Rightarrow$ To form smallest 6-digit number, we have to start number with smallest digit and end with largest digit.

$\Rightarrow$ Here, we can not use $0$ as first digit because then number will becomes 5 digit.

$\therefore$ The smallest 6-digit number = $1,05,689$.
