Answer:
(C)On a coordinate plane, 2 rays form an angle. One ray sits on the x-axis.
Explanation:
An angle is stated in the standard position with respect to the x-axis.
Therefore, for an angle to be in standard position, one of its rays must be on the x-axis.
From the given options, only Option C has a ray on the x-axis and therefore is the angle that is in standard position.
