✔ 最佳答案
ans應該係b因為最下面gei incident ray 係由object gei最低點出發,,
所以佢都應該o係番image gei最低點,, 而唔係tip of it
上面2絛incident ray都係咁,,, 由tip of object 出發,, 所以forms the tip of image

Concave Lens 係分散光散光線
係c同d度,由底出黎既光線係聚焦
而且個image 一定係virtual,erect and same side of the object
呢個係convex lens 既特性
所以reject C,D
o係A 度,由底出黎既光線唔會form o係個image個頂度
應該底去底,頂去頂,咁先見晒成個image
所以a都 reject
b 乜都冇錯,又係virtual,erect and same side of the object
光線又個分散
底出黎既光線又去番底
所以ans 係b
