The amount of heat absorbed by one mole of an ideal gas in an isochoric process to raise the temperature from $1\mathrm{.}1C$ to $11\mathrm{.}1C$ is $120k\frac{J}{m}ol.$ The $Cv$ and $Cp$ values of the gas in $k\frac{J}{m}$olK will be:

$($a$)12kJ$&$3\mathrm{.}7kJ$

b$)10kJ$&$12kJ$

c$)12kJ$&$20\mathrm{.}3kJ$

d$)20\mathrm{.}3kJ$&$12kJ$
