the heat absorbed by the gas from the surrounding is $600\,J$

(B) For an isothermal process,the temperature remains constant,so the change in internal energy $dU = 0$.According to the first law of thermodynamics,$dQ = dU + dW$.Given that the gas does $600\,J$ of work,$dW = 600\,J$.Substituting these values,$dQ = 0 + 600\,J = 600\,J$.Since $dQ$ is positive,the gas absorbs $600\,J$ of heat from the surroundings.
