To find the gravitational force of attraction between the planet and the 17-kilogram mass, we can use the formula for gravitational force:

\[ F = m \cdot g \]

Where:
- \( F \) is the gravitational force (in Newtons),
- \( m \) is the mass (in kilograms),
- \( g \) is the acceleration due to gravity (in m/s²).

In this case:
- \( m = 17 \, \text{kg} \)
- \( g = 8.8 \, \text{m/s}^2 \)

Now we can substitute the values into the equation:

\[ F = 17 \, \text{kg} \cdot 8.8 \, \text{m/s}^2 \]

Calculating this:

\[ F = 149.6 \, \text{N} \]

Rounding this to the nearest whole number gives us:

\[ F \approx 150 \, \text{N} \]

Therefore, the gravitational force of attraction between the planet and the 17-kilogram mass is approximately **150 N**.

The correct answer is:
**a 150 N**.
