Hai, I am sairam.
Temperature is a degree of measure of hotness or coldness of a body. Then how can temperature changes in constant heat (adiabatic) process?

In adiabatic process no heat enter and lease system then work done by or on the system is zero.
dQ=0 then dW=0 As per first law of thermodynamics.
dQ=0 then dW=0 As per first law of thermodynamics.

The answer is correct because temperature variation takes place inside the system. Any way it won't transfer to outer area hence it has sealed.

In this process no heat is added or withdrawn from the system so how another process can happen only a option is true another one is wrong.

Internal energy is a function of temperature so temperature must be change. For more information refer adiabatic free expansion process.

In Option B, Temperature of system changes with heat addition or Rejection. How could it possible?
I think the Option A is correct.

An adiabatic as no heat added then dw = 0.
dq = du+dw.
dq = 0, dw = 0.
So du = 0.
=> du = dw process the work done is zero.
dq = du+dw.
dq = 0, dw = 0.
So du = 0.
=> du = dw process the work done is zero.

If temperature of the gas changes then there will be some heat change or transfer, in that case how process will be adiabatic?

Temperature will change only in form of work done by system (decrease in temp) , or work done on system (increase in temp).

Adiabatic process is the transfer of energy as the work, with out transfer of heat between its system and surroundings.
