Option $(a)$ is wrong ; since in adiabatic process $V \neq$ constant

Option $(b)$ is wrong, since in isothermal process

$T = constant$

Option $(c)$ and $(d)$ matches isothermes and adiabatic formula :

$TV ^{\gamma-1}=$ constant and $\frac{ T ^{\gamma}}{ p ^{\gamma-1}}= constant$

    If heat is added at constant volume, $6300\,\,J$ of heat are required to raise the temperature of an ideal gas by $150\,\,K$. If instead, heat is added at constant pressure, $8800$ joules are required for the same temperature change. When the temperature of the gas changes by $300\,\,K$, the internal energy of the gas changes by ..... $J$

    An engine runs between a reservoir at temperature $200 \,K$ and a hot body which is initially at temperature of $600 \,K$. If the hot body cools down to a temperature of $400 \,K$ in the process, then the maximum amount of work that the engine can do (while working in a cycle) is (the heat capacity of the hot body is $1 \,J / K )$
