An inverted image can be seen in a convex mirror:

The convex mirror is shown in the figure below-

This convex mirror has a silver color (a coating that gives the light characteristics of glass) inside and can be seen as the film on the right side of the picture above. A unique and interesting feature of the
convex mirror is that the constructed image is always straight, regardless of whether the object is in front of the convex mirror.
Let's talk about real images

As we saw in this scenario, the images are real and small, but especially distorted. This is the shape of the image structure of the actual object placed somewhere in front of the convex mirror. In, let's talk about photography. 

As we saw in the photo, in this case the photo is real, magnified, but still standing. This is the shape of the image of any visible object at any distance from the convex mirror.
Therefore, as we saw in the two cases above, the convex mirror always produces a straight image.
Therefore, the Correct Option is 1
