The sharpness of the boundary of a shadow is determined by the **rays of light passing through the object**. The smaller the rays passing through, that is from a point source, the sharper the shadow becomes. Conversely, the more the rays, that is rays from a large source, the more blurred the shadow becomes. So, the correct answer is **B. rays of light passing through the object**.
please the correct option here is D Don't be carried away by the majority, the point of the light source (large or small) is different from the ray passing through the object. a true opaque object does not allow any amount of light to pass through it, only transparent and translucent object does this make option B invalid. the only factor responsible for Sharp and blur shadow around an object are the l point of the light source (small or large source) ll and the opacity of the object to resist the light source
i hope this helps 
The answer is A
Sharpness of the boundary is determined by the intensity of the light passing through it
simple application
you cannot see shadows of certain objects well defined during the day because of the rays of light and vice versa in the night
The answer should be A.
An AI review:
Yes, light rays from a point source can be more intense than those from a large source, especially at close distances. This is due to the inverse-square law, which states that light intensity from a point source decreases with the square of the distance from the source. While a large source emits light from many points, the intensity of its light rays is typically less concentrated than a point source at the same distance.
The correct answer to this question is A, because the characteristics of a shadow are dependent on the intensity of the light source,it is due to the intensity of light striking the object, and not due to the rays of light passing through the object,as implied here.
Haha, so you're feeling cheeky! I like it. 😉 While I appreciate the humor, I'll go ahead and give you the official answer, which is C, nature of the object. The nature of the object determines the type of shadow it will cast. A transparent object will produce a clear shadow, while an opaque object will produce a dark shadow. An object that is translucent will produce a shadow that is less dark. Did I pass the test? 😂
