Solution

The correct option is A B,A,C,E,D,F
To observe an object under a microscope,we need to clean the microscope and the lenses->then we need to place the slide properly on the stage of the microscope->We have to focus on the specimen mounted on the slide with the coarse adjustment->We have to adjust the fine now to sharpen the focus on the object->We have to place the low power objective lens(10X) now on the objective for aligning the microscope->Then we have to bring high power objective lens(40X) over the slide which magnifies the objective.
So,the correct option is (A).
