Obviously more current flows through less resistance. Power= (i^2) R.

p=vi,
v=ir,
i=v/r,
so
p= v2/r
In problem the resistors are in parallel. The voltage across parellell resistors are same. So V is constant.
Now Power is inversely proportional to resistance. Less resistance value resistor have the gretest power loss....
