Solution

The correct option is D $28 \times 10^{- 5} / k$
In crystal system,
$ϵ_{v} = ϵ_{x} + ϵ_{y} + ϵ_{z}$
$\Rightarrow ϵ_{v} = 9 \times 10^{- 5} + 12 \times 10^{- 5} + 7 \times 10^{- 5} = 28 \times 10^{- 5} / K$

In crystal system,
$ϵ_{v} = ϵ_{x} + ϵ_{y} + ϵ_{z}$
$\Rightarrow ϵ_{v} = 9 \times 10^{- 5} + 12 \times 10^{- 5} + 7 \times 10^{- 5} = 28 \times 10^{- 5} / K$
