Hint: Most of the inner lining of hollow structures of the body is composed of epithelial tissues and vascular bundles are present in plants and not in another organism. Rest can be named by their organ.

Complete answer:
Since it is clear that the vascular bundles are the part of plants which is an interconnected network of various tissues. These are the tissues which have to be permanent in the plants so as to carry out the regular functions required by the plants. The xylem and phloem are the part of the vascular bundles and they are too formed of the permanent tissues and they generally are known as complex permanent tissues.
If you remember the embryology part of your studies, how the inner lining of the embryo gets developed into the entire organ system of the human body. It is that ectoderm layer which is responsible for differentiation into the epithelium layer which will be forming the hollow organs of the body including kidney, lungs, stomach, intestines. The tissue which then forms the inner lining of the hollow organs is the cuboidal epithelium tissue.
We know that the contraction of the iris is important because it is responsible for the contraction and expansion of the pupil so that the right amount of light can enter inside the eye. The muscle which is responsible for the movement is the ciliary muscle formed of the striated muscular tissues.
Heart is an involuntary organ and we all know this, so the muscles and tissues of the heart are also different from the other organs. The muscles mainly responsible for contraction of heart are the cardiac muscles and they are formed of the cardiac tissues.

Hence, a - Complex Permanent Tissue, b, d, f – Cuboidal Epithelial Tissue, c – Striated muscular tissue, e – Cardiac muscular tissue.

The muscles which work on their own generally have tissues with muscles named only and the tissue lining the organs can be remembered by studying about the embryology of the body.
