Answer:
there is a diagram in the question expect that we cannot answer 'cause you didn't show it and it is asking you for the image formed by the mirror if the object is kept at a distance of 10 cm from the mirror and the 20 cm .........................hope you have got your answer...................if it's a plane mirror then image will for 40 cm away from the object of 20 cm distance and 20cm away from the object of 10 cm distance.................
Hmm, I was stuck on this question during my 10th std days aswell, memories recalled :)
Ps. This is a very subjective and controversial question, there can be many ways to define a mirror's suitability for the purpose, most important of which is the distance from which the mirror is held from the face.
Taking this into consideration, mirror C is the most suitable, because of its large focal length, an erect and magnified image can be formed comfortably from the face, and it's harder to do so in mirror B and hardest in mirror A.
Hope it helps!
Have a nice day brother/sister!! ^_^
