I'll assume that you mean using a simple magnifying glass
to magnify things, not to burn ants or ignite newspaper.
When a magnifying glass is used to magnify ... for example,
to inspect the markings on a dime, or to read the fine print
in an insurance policy ... no image is formed. That is, no real
image. It's called a 'virtual image'. It's erect, and it's on the same
side of the glass as the object being examined.
Magnifying glasses typically use a value of 0.25 meters, or 250 millimeters, distance. This means that that D is the correct answer and the image will be formed approximately D. 250 millimeters in front of the lens
