Final answer:
A transformation that produces a similar figure is a dilation, and the closest term among the given options is 'Enlargement'. Other options such as translation, rotation, and contraction are transformations but don't imply a change in size.
Step-by-step explanation:
A transformation that produces a similar figure, which means a figure that has the same shape but potentially a different size, is called a dilation. Among the options given, none are precisely the term for dilations, but choice d) Enlargement is the closest term that implies a similar figure. An enlargement implies a change in size but not in shape, which is consistent with the effects of a dilation. A dilation can also reduce the size of a figure, and in such a case, it might be called a contraction, but since this option is not a universal term for all dilations, enlargement is the closest match. Translation, rotation, and contraction are other forms of transformations, but they do not necessarily produce similar figures with different sizes; instead, they move or rotate the figure without altering its size or shape.
