Correct. Snow in Ladakh in November is unlikely. Ladakh is a desert, of course, so there's very little precipitation at any time, and November tends to be clear. If it gets cloudy it can snow on the passes to Nubra or Pangong, but if it snows heavily on those passes, the authorities close them. You can probably see snow on the ground up there, though.
Friends Please suggest me which is best option for travelling to Leh (99% I am planning Manali - Leh - Srinage)

this date are fixed departure tour package...
The other way round should be better i.e. Srinagar-Leh-Manali in terms of acclimatization. September plan would do good if you are trying to minimize the chances of rain enroute but the possibility of snow at high passes eventually disappears as well.
