Read of following statements regarding different types of animal tissues and select the incorrect ones.
(i) Each fasciculus (or bundle of muscle fibres) is surrounded by an epithelial tissue covering called perimysium
(ii) Multi unit smooth muscles are present in ciliary and iris muscles in the eyes and muscles of the walls of large bloood vessels
(iii) Columnar epithelium present in gastric glands, intestinal glands, intestinal glands and pancreatic lubules, has a secretory role and is called as glandular epithelium
(iv) Epithelial tissue arises only from the ectoderm of embryo and is usually supplied with blood vessels.

Options

A. (i) and (iii)
B. (ii) and (iii)
C. (ii) and (iv)
D. (i) and (iv)

Explanation

To determine the incorrect statements regarding different types of animal tissues, let's analyze each statement one by one.

1. **Statement (i)**: "Each fasciculus (or bundle of muscle fibres) is surrounded by an epithelial tissue covering called perimysium."
- **Analysis**: This statement is incorrect. The fasciculus, which is a bundle of muscle fibers, is actually surrounded by a connective tissue covering known as perimysium, not epithelial tissue. Therefore, this statement is false.

2. **Statement (ii)**: "Multi unit smooth muscles are present in ciliary and iris muscles in the eyes and muscles of the walls of large blood vessels."
- **Analysis**: This statement is correct. Multi-unit smooth muscles are indeed found in the ciliary and iris muscles of the eyes, as well as in the walls of large blood vessels.

3. **Statement (iii)**: "Columnar epithelium present in gastric glands, intestinal glands, and pancreatic lobules has a secretory role and is called glandular epithelium."
- **Analysis**: This statement is also correct. Columnar epithelium found in these glands does have a secretory function and is classified as glandular epithelium.

4. **Statement (iv)**: "Epithelial tissue arises only from the ectoderm of the embryo and is usually supplied with blood vessels."
- **Analysis**: This statement is incorrect. Epithelial tissue arises from all three germ layers: ectoderm, endoderm, and mesoderm. Additionally, epithelial tissue is typically avascular (lacks blood vessels) and receives nutrients through diffusion from underlying connective tissues.

**Conclusion**: The incorrect statements are (i) and (iv).

### Summary of Incorrect Statements:
- Statement (i) is incorrect because perimysium is a connective tissue covering, not epithelial.
- Statement (iv) is incorrect because epithelial tissue arises from all three germ layers and is usually avascular.
