I understand that there is no current though the 1KΩ resistor but I don't understand why the 1.5KΩ resistor doesn't have current thought them...

is it because of KVL? since there is no voltage across the 1.5kΩ resistor thus the current must be zero?

The 1.5k resistor does not have any current going through it because it seems to be shorted -- both terminals of the resistor are tied together.

What does the shorted exactly mean? or what happened when shorted?

other components create a path for current so that it bypasses the component - look closely at the nodes (a,c,d) and how it is wired, do you notice anything?

As I said in my message, "shorted" means that both terminals of the resistor are tied together and therefore there is no voltage across the resistor. As a result the current through the resistor is zero due to Ohm's law
i=V/R=0/R=0A.
