Explanation:

Certainly! Here's an explanation of the statements and options:

- C: This statement introduces International Tiger Day and provides context about its inception at the Saint Petersburg Tiger Summit in 2010.

- D: This adds to C by giving the date and purpose of the event – to raise awareness about tiger conservation.

- B: Follows logically by explaining the primary objective of the event, which is to preserve the natural habitat of tigers.

- A: Provides additional detail and examples of where and how the event is observed, specifically mentioning India, Bangladesh, and Nepal.

Now, let's look at the options:

1. CDBA: This sequence correctly narrates the initiation, purpose, objective, and regional impact of International Tiger Day.

2. BACD: This would start with a specific fact about tiger populations, which isn't logically the first step in introducing International Tiger Day.

3. CABD: Starts correctly with C but places B before D, creating a less coherent flow between the introduction and the description of the event.

4. DCBA: Starts with D, missing C’s context about the historical inception of the day, making it a less cohesive choice.

- Correct Answer: 1, CDBA
