Question

In nematode taxonomy, the de Man's ratio c' is

• A. body length tail length
• B. body length oesophageal length
• C. tail length body width at anus
• D. tail length maximum body width

Hint:

To avoid confusion among the de Man's ratios:
- Primeless indices (\( a \), \( b \), \( c \)) always use the total body length in the numerator.
- Primed indices (like \( c' \)) use a specific organ measurement (like tail length) in the numerator to establish a local proportional relationship.

Answer 1

The Correct Option is C
