\[ \begin{aligned} \text{I.} \;& \textit{Homo sapiens sapiens} \\ \text{II.} \;& \textit{Axis axis} \\ \text{III.} \;& \textit{Corvus splendens splendens} \\ \text{IV.} \;& \textit{Naja naja} \end{aligned} \]

• B. I, II, III, IV
• C. I, III, IV only
• D. II, IV only

Hint:

Examples of tautonyms: \[ \boxed{ \textit{Axis axis},\; \textit{Naja naja},\; \textit{Gorilla gorilla} } \]

Answer 1

The Correct Option is D

Step 1: Recall the meaning of tautonym. A tautonym is a scientific name in which the generic name and specific epithet are identical. \[ \boxed{\textit{Genus = Species}} \]

Step 2: Examine each name. \[ \begin{aligned} \textit{Homo sapiens sapiens} &\rightarrow \text{Not a tautonym} \textit{Axis axis} &\rightarrow \checkmark \textit{Corvus splendens splendens} &\rightarrow \text{Not a tautonym} \textit{Naja naja} &\rightarrow \checkmark \end{aligned} \]

Step 3: Choose the correct option. Therefore, \[ \boxed{(D)\ \text{II and IV only}} \] is the correct answer.
