How does quantum theory explain blackbody radiators?
oa. as heat is added, additional photons across a wide range of
visible-light frequencies are emitted.
ob. raising the temperature results in the object giving off high-energy
ultraviolet light.
oc. as heat is added, only certain specific temperature values are
possible.
od. raising the temperature causes more photons of a few specific
energies to be emitted.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
