According to man page of dfu-util 0.5 (supports DFU v1.0):
"-a"  can be used Specify the Altsetting of the DFU Interface by name or
by number

So since "MLO" is the name for alt setting 0 both
sudo dfu-util -D MLO -a MLO  and
sudo dfu-util -a 0 -D MLO  are correct.

I used the above format as its easier for reading. Thanks!
