Correct Answer:
D. 2
Explanation:
The linear magnification ($m$) of an image is defined as the ratio of the image height ($h_i$) to the object height ($h_o$), expressed by the formula $m = h_i / h_o$. In this scenario, the height of the image is specified as being twice the height of the object ($h_i = 2h_o$). By substituting these values into the formula, we get $m = 2h_o / h_o$, which simplifies to 2. Therefore, a linear magnification of 2 indicates that the image is twice as large as the original object.
