Detailed Solution

Step 1: Analyze Statement I

The term Reptilia is derived from the Latin word repere or reptum, which means to creep or crawl. This refers to the characteristic mode of locomotion observed in members of this class. Therefore, Statement I is correct.

Step 2: Analyze Statement II

While most reptiles (such as lizards and snakes) possess a three-chambered heart, this is not a universal trait for all organisms in the class. Crocodilians (order Crocodilia) possess a four-chambered heart. Since the statement claims all organisms have a three-chambered heart, it is factually incorrect. Therefore, Statement II is incorrect.

Step 3: Conclusion

Since Statement I is correct and Statement II is incorrect, the appropriate option is (D).

Final Answer: Statement I is correct but Statement II is incorrect
