You need to draw two lines from the head of the arrow: one parallel to the axis (which will be bent) and the other one passing through the center of the converging lens <span>(which will continue straight) </span>and see where they intersect.
If the arrow is at an infinite distance, the image will be point-like in F. If the arrow is at a distance greater than 2F, the image will be upside down between F and 2F. If the arrow is at a distance of 2F, the image will be upside down in 2F. If the arrow is at a distance between F and 2F, the image will be upside down beyond 2F. If the arrow is at a distance F, all rays proceed parallel to each other and no image is formed. If the arrow is at a distance smaller than F, the image will be virtual.
Therefore, the correct matches are 1B, 2C, 3D, and 4A.
