Answer
a). A spoon can behave as either a concave or a convex mirror depending on which side you use for reflection. If you use the concave side, you normally see an inverted image. If you use the convex side, you always see an upright image.
b). In theory, the answer is yes. If you are very close to the spoon on the concave side, an upright image exists.
Although, it may be difficult to see the image in practice, as the eyes are too close to the image.
