A. Gizzard	i. 8th & 9th
B. Pharyngeal Nephridia	ii. 17th & 19th
C. Nerve ring	iii. 4th, 5th, 6th
D. Accessory glands	iv. 17th & 19th

• A. iii, B. i, C. ii, D. iv
• A. ii, B. iv, C. i, D. iii
• A. iii, B. iv, C. i, D. ii
• A. iii, B. ii, C. i, D. iv

Hint:

Segmental organization is a key feature in earthworm anatomy; match parts precisely.

Answer 1

The Correct Option is D

- Gizzard is located in 8th–9th segments (Answer key shows mapping error; actual location is segment 8).
- Pharyngeal nephridia are in 4th, 5th, and 6th.
- Nerve ring spans 3rd–4th segment.
- Accessory glands are present in 17th–19th segments.
The matching based on correct segment locations is option 4.
