Solution

The correct option is B False
 solution:

  monoatomic diatomic
 $$f$$ $$3$$ $$5$$
 $$C_v$$
 $$\dfrac{3R}{2}$$ $$\dfrac{5R}{2}$$
  $$C_p$$ $$\dfrac{5R}{2}$$ $$\dfrac{7R}{2}$$
$$\gamma$$    = 1.67      for monoatomic                     
$$\gamma$$    = 1.40      for diatomic                 
hence the statement is false 
the correct opt: B
