The normal force is the force exerted by a surface that supports the weight of an object resting on it. It acts perpendicular (or "normal") to the surface. The normal force is equal to the weight of the object, so we can calculate it using the formula:

Normal Force = mass * gravity

Where the mass is 13 kg and the acceleration due to gravity is approximately 9.8 m/s².

So, Normal Force = 13 kg * 9.8 m/s² = 127.4 N

However, none of the options exactly match this result. The closest one is option B. 99.4 N. But if we consider the standard value of gravity as 10 m/s² for simplification, we get Normal Force = 13 kg * 10 m/s² = 130 N, which is still not in the options.

Therefore, it seems there might be a mistake in the question or the provided options.
