This is because y is also called X=0 and x=0,y=3 so it will lie on positive y axis(+ve y axis)

The point (0, 3) lies on the y-axis.

Explanation:
To understand why the point (0, 3) lies on the y-axis, let's first review the coordinate system.

The Coordinate System:
The coordinate system is a grid that helps us locate points in space. It consists of two perpendicular lines called the x-axis and the y-axis. The point where these two axes intersect is called the origin, denoted as (0, 0).

The x-axis:
The x-axis is the horizontal line on the coordinate plane. It represents the values of x, where x can be any real number. The x-axis is labeled from left to right, with negative values on the left side of the origin and positive values on the right side.

The y-axis:
The y-axis is the vertical line on the coordinate plane. It represents the values of y, where y can be any real number. The y-axis is labeled from bottom to top, with negative values below the origin and positive values above.

The Point (0, 3):
The point (0, 3) has a x-coordinate of 0 and a y-coordinate of 3. Since the x-coordinate is 0, it means that the point lies on the y-axis. The y-coordinate of 3 indicates that the point is 3 units above the origin.

Conclusion:
Based on the given coordinates of (0, 3), we can conclude that the point lies on the y-axis. Therefore, the correct answer is option B: the point (0, 3) lies on the y-axis.
