The answer is velocity.
The momentum vector has the same direction as the velocity vector.
Momentum is the product of velocity and mass; and since velocity is the only vector in this product, momentum has the same direction as the velocity.
velocity
acceleration
. . . the object's velocity.
The velocity.
velocity
A feather with no momentum maintains constant velocity. Momentum is defined as the quantity of motion of a moving body, measured as a product of its mass and velocity.
As far as we can tell, it doesn't. Momentum is defined as (mass) times (velocity). There appear to be only two ways in which momentum can decrease: either the mass has to magically evaporate, or else the velocity has to decrease. Since mass conservation is a nearly fundamental law of nature, that leaves us with velocity as the only way to change the momentum of a moving body.
Momentum is defined as the quantity of motion of a moving body, measured as a product of its mass and velocity. It is a conserved quantity and within an isolated system the total momentum is constant.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.

The velocity of the car is staying constant speed the whole time. It is not rising or diminishing at all.

Not necessarily. Constant velocity also means no change in direction.

Acceleration is the CHANGE in velocity; you're assuming CONSTANT velocity. So the acceleration is zero.
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
constant speed means no acceleration and thus no change in velocity

determine if the momentum of an object moving in a circular path at constant speed is constant.
Momentum depends on mass and velocity.
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
