{'concave mirror': [0, 0, 2, 6], 'curvature': [0, 0, 1, 0], 'principal focus': [0, 0, 1, 2], 'centre': [10, 3, 7, 19], 'curvaturc': [0, 0, 1, 0], 'position': [3, 2, 7, 11]}

Option 1 states that the position of the image is at the principal focus. When an object is placed at the centre of curvature of a concave mirror, the image is formed at the same location as the object. This means that the image is at the centre of curvature, not at the principal focus. Therefore, option 1 is incorrect.

Option 2 states that the position of the image is between the principal focus and the centre of curvature. This option is also incorrect because the image is formed at the centre of curvature, not between the principal focus and the centre of curvature.

Option 3, which is the correct answer, states that the position of the image is at the centre of curvature. When an object is placed at the centre of curvature of a concave mirror, the rays of light that are reflected from the mirror converge at the same point, resulting in the formation of an image at the centre of curvature.

Option 4 states that the position of the image is beyond the centre of curvature. This is incorrect because the image is formed at the centre of curvature, not beyond it.

In conclusion, the correct answer is option 3, which states that the position of the image is at the centre of curvature.
