A concave mirror of small aperture forms a shaper image. Why?

A concave mirror always forms a real image. (T/F)

A kid of height 1.1 ft is sleeping straight between focus and centre of curvature along the principal axis of a concave mirror of small aperture. His head is towards the mirror and is 0.5 ft from the focus of the mirror. How a plane mirror should be placed so that the image formed by it due to reflected light from concave mirror looks like a person of height 5.5 ft standing vertically. Draw the ray diagram. Find the focal length of the concave mirror.

Concave mirrors A and B each focal length - 15 cm. Concave mirror A has a larger aperture than B. Which of these will form a sharper image ? Why ?
