When a moving object reduces its speed, what happens to the objects acceleration in relation to its velocity?

-- When the object's acceleration is in the same direction
as its velocity, the object's speed increases.

-- When the object's acceleration is in the direction opposite to
its velocity, the object's speed decreases.

-- When the object's acceleration is in the direction perpendicular
to its velocity, its speed doesn't change, but its direction does.

Ibelieve the answer is d. macula  hope my answer has you : )

It was crowded with sewer like smells. bad sewer systems
