The correct answer is $(d)$. Between the pole of the mirror and its principal focus.

Formation of an image$(virtual,\ erect,\ and\ larger\ than\ the\ object)$

The image formed by a concave mirror is observed to be:

• Formation of a virtual image $\rightarrow$

The image formed by a concave mirror is virtual if the object is placed in front of the focal point.

• Formation of an erect image$\rightarrow$

The image formed by a concave mirror is erect if the object is placed between the pole and the focus of the concave mirror.

• Formation of a magnified image$\rightarrow$

The image formed by a concave mirror is larger than the object only if the object is placed between the pole of the mirror and its principal focus.

Conclusion$\rightarrow$

Therefore, the image formed by a concave mirror will be virtual, erect, and larger than the object only when the position of the object is placed between the pole of the mirror and its principal focus.

So, option $(d)$ is correct.
