There are some lenses available in the laboratory as follows. To magnify the specimen under observation by 50 times, the lenses that should be chosen are ( ) A. ③ and ⑥ B.

The lenses of a microscope are the eyepiece and the objective lens. The objective lens is mounted on a transducer, so the objective lens has a screw pattern. The objective lens is mounted on a converter, so the objective lens has a screw pattern. The eyepiece is placed directly in the barrel, so the eyepiece is not threaded. Therefore, ③ ④ ⑥ is the eyepiece and ① ② ⑤ is the objective lens. The magnification of the microscope is equal to the product of the magnification of the eyepieces and objective lenses, according to which, in order to make the object being observed 50 times larger, should choose the lens ① and ③.
