Final answer:

The magnification of the bug's image in the photo is 16.14 times the actual size of the yellow shield bug, with the photo showing an 11.3 cm long image of a bug that is typically 7 mm in length.

Step-by-step explanation:

The student asked about the magnification of an image of a yellow shield bug that Pritesh found in a photo. To calculate the magnification, we need to compare the actual size of the bug to the size of the image in the photo. Given that the photo shows the bug at 11.3 cm and the actual size of the bug is 7 mm, we first need to convert the units so they match. Since 1 cm = 10 mm, we convert 11.3 cm into mm, which gives us 113 mm.

The magnification can then be calculated by dividing the size of the image by the actual size of the bug:

Magnification = Image size / Actual size = 113 mm / 7 mm = 16.14 times.

Therefore, the magnification of the bug's image is 16.14 times, which corresponds to option (b).
