(a) Oesophagus
(b) Gizzard
(c) Stomach
(d) Intestine

Options

A. Oesophagus
B. Gizzard
C. Stomach
D. Intestine

Answer

To solve the question "Which of the following parts of gut occupies most part of the 8th segment?" we can follow these steps:

### Step 1: Understand the Context
The question is related to the anatomy of the earthworm, specifically focusing on the segments of its gut. The earthworm has a segmented body, and each segment may contain different parts of the digestive system.

**Hint:** Remember that the earthworm's body is divided into segments, and each segment can house different organs of the digestive system.

### Step 2: Identify the Relevant Parts of the Gut
The options provided are:
(a) Oesophagus
(b) Gizzard
(c) Stomach
(d) Intestine

We need to determine which of these parts is located in the 8th segment of the earthworm.

**Hint:** Think about the order of the digestive organs in the earthworm and where they are located in relation to the segments.

### Step 3: Recall the Segment Occupation of Each Gut Part
From the information provided:
- The **oesophagus** occupies segments 5 to 7.
- The **gizzard** occupies segments 8 to 9.
- The **stomach** occupies segments 10 to 12 or 13.
- The **intestine** starts from segment 14 or 15 onwards.

**Hint:** Visualize the digestive tract of the earthworm and remember the segment ranges for each organ.

### Step 4: Determine Which Part Occupies the Most of the 8th Segment
Since the gizzard is specifically mentioned to occupy segments 8 to 9, it is clear that the gizzard occupies the most part of the 8th segment.

**Hint:** Focus on the specific segment mentioned in the question (8th segment) and identify which organ is primarily located there.

### Step 5: Conclusion
Based on the analysis, the part of the gut that occupies most of the 8th segment is the **gizzard**.

**Final Answer:** (b) Gizzard
