Dude uve got something wrong in your brain or what even if pressure and vol. remain same number of collisions will increase caz there increasing the temp..avg k.e increases number of collisions per second also increase..common thing..if think that D does not occur. then A should be right as well caz they said avg..speed increases..thing is i chose C caz i eliminated the other options..and the other 3 were definitly incorrect..the pressure remains the same coz they pulled out the piston. So the volumes has increased by pulling out the piston BUT since the pressure is same the frequency of collisions will not increase. so the ans is D
