Point (5, 5/3) has polar coordinates (2√10/3, 19.1°) and (2√10/3, 199.1°) due to angle ambiguity. So the correct option is B.

The question asks you to:

1. Plot the point with rectangular coordinates (5, 5/3).

2. Give two pairs of polar coordinates for the point, where 0° < θ < 360°.

To convert rectangular coordinates to polar coordinates, you can use the following formulas:

* r = √(x² + y²)

* θ = tan^-1(y/x)

For the point (5, 5/3), you would get:

* r = √(5² + (5/3)²) = √(40/9) = 2√10/3

* θ = tan^-1((5/3) / 5) = tan^-1(1/3)

There are two solutions for θ in the range 0° < θ < 360°:

* θ1 = 19.1°

* θ2 = 199.1°

Therefore, two possible pairs of polar coordinates for the point (5, 5/3) are:

* (2√10/3, 19.1°)

* (2√10/3, 199.1°)

The plot of the point and the two possible polar coordinates is shown in the image you sent.

The correct answer is (b) (2√10/3, 19.1°), (2√10/3, 199.1°).
