Correct Answer: $\frac{4}{\sqrt3}$

Solution :
Given: $\triangle$XYZ is right angled at Y and $\angle$X = 60°.
$(\sec Z+\frac{2}{\sqrt3})$
= $(\sec(90°-60°)+\frac{2}{\sqrt3})$
= $(\sec30°+\frac{2}{\sqrt3})$
= $(\frac{2}{\sqrt3}+\frac{2}{\sqrt3})$
= $\frac{4}{\sqrt3}$
Hence, the correct answer is $\frac{4}{\sqrt3}$.
