The horizontal component of velocity determines the greatest height and when the lauch angle is 90 degree, the horizontal component is maximum.
An angle is a figure in Plane Geometry formed by two rays or lines that share a common endpoint. "Angle" comes from the Latin word "angulus," which means "corner." The two rays are referred to as the sides of an angle, and the common endpoint is referred to as the vertex.
Therefore, the correct answer is option a) [tex]90^{\circ}[/tex].
