If $\;du_{1}\;,du_{2}\;,du_{3}\;$ are change in internal energy of gas in isobaric , isothermal and adiabatic processes , then for the same change in temperature

Question

$(a)\;du_{1} > du_{2} > du_{3}\qquad(b)\;du_{1} < du_{2} < du_{3}\qquad(c)\;du_{1} = du_{2} = du_{3}\qquad(d)\;du_{2} < du_{1} < du_{3}$
