A body moving with constant speed in a straight line means its velocity is constant (both magnitude and direction are unchanging). This type of motion is defined as uniform motion.
a) Accelerated motion* involves a change in velocity (either speed or direction).
b) Uniform motion* means constant velocity, which includes constant speed in a straight line.
c) Circular motion* involves a continuous change in direction, even if the speed is constant, meaning it is accelerated motion.
d) Random motion* implies unpredictable changes in speed and/or direction.
Therefore, the correct option is (b).
The final answer is $\boxed{\text{B}}$
