The Correct Option is B

Solution and Explanation

Trachea and large bronchi are lined by pseudo stratified ciliated columnar epithelium bearing glandular cells (mucous gland). The secretion of mucous glands keeps the walls of trachea and large bronchi moist and traps dust particles which enter with the air. The vibratile cilia of the epithelium then carry the mucous containing dust particles upto the larynx where they can be spitted out.

Animal Tissues

Human bodies, like most animal bodies, are made up of four different types of tissue:

Epithelial Tissue:

This tissue forms the outer layer of the body and also lines many of the body's cavities where it has a protective function.

General functions of epithelial tissue:-

  1. Provides a barrier between the external environment and the organ that it is covering.
  2. Specialized to function in secretion and absorption.
  3. Protects organisms from microorganisms, injury, and fluid loss.

Connective Tissue:

This tissue assists in the support and protection of organs and limbs and depending on the location in the body it may join or separate organs or parts of the body.

Muscle Tissue:

This tissue enables various forms of movement, both voluntary and involuntary.

Nerve Tissue:

This tissue is responsible for the carrying of electrical and chemical signals and impulses from the brain and central nervous system to the periphery, and vice versa.
