Engineering Thermodynamics
Relation between cp and cv is given by (where cp = Specific heat at constant pressure, cv = Specific heat at constant volume, γ = cp/cv, known as adiabatic index, and R = Gas constant)

cv = R/ γ-1

Both (B) and (C)

cp - cv = R

cv/ cp =R

cv = R/ γ-1

Both (B) and (C)

cp - cv = R

cv/ cp =R
