Answer: A

Explanation:

$\stackrel\frown{XY}$ ≅
$\stackrel\frown{YZ}$

⇒ ∠XOY ≅ ∠ZOY

$\overline{XO}$ ≅
$\overline{ZO}$ since they are both a radius

$\overline{OY}$ ≅
$\overline{OY}$ based on reflexive property

∴ ΔXOY ≅ ΔZOY by SAS

So,
$\overline{XY}$ ≅
$\overline{ZY}$ by CPCTC

ZY = 10.2 is given

so, XY = 10.2 by substitution property
