• C.

• D.
  XA is a ray

Answer 1

Answer: (A), (B)

The correct options are
A
XO is a ray
B

CD is a line segment
It can be seen that XO starts at X and extends endlessly in the direction of O.
$\therefore$ XO is a ray.

CD has two endpoints and has a fixed length.
$\therefore$ CD is a line segment

OD and OC have fixed lengths and have two end points.
$\therefore$ They are line segments and not rays.

XA has two endpoints and has a fixed length.
$\therefore$ XA is not a ray , it is a line segment
