Answer 2

d)270 is the correct answer.

Explanation,

• Let us imagine a cartesian plane. We are asked to go from the x-axis to the y-axis travelling clockwise. In total, there are four quadrants in the cartesian plane. Two lines perpendicular bisector to each other divide it into four equal parts.

• Each quadrant covers an angle of 90 degrees. We start from the x-axis, and after covering the complete quadrant, we reach the y-axis. After that covering one quadrant, we are on the negative x-axis. Another quadrant and we reach our desired y-axis.

In total, we covered three quadrants. Therefore, the total angle covered will be 3*90 = 270 degrees.
