The correct Answer is:
To solve the question regarding the extinction of giant mammals, we need to analyze the options provided and determine the correct time period in which these extinctions occurred. Here’s a step-by-step breakdown: ### Step 1: Understand the Question The question asks about the time period during which giant mammals became extinct. We need to identify the correct geological epoch from the options given. ### Step 2: Review the Options The options provided are: - (a) Pleistocene-Holocene - (b) Pliocene-Pleistocene - (c) Eocene-Oligocene - (d) Pliocene-Miocene ### Step 3: Identify the Extinction Period Giant mammals, often referred to as megafauna, are known to have gone extinct around 10,000 to 12,000 years ago. This timeframe corresponds to the end of the last Ice Age, which is primarily associated with the Pleistocene epoch. ### Step 4: Analyze Each Option - **Option (a) Pleistocene-Holocene**: This period includes the end of the Pleistocene and the beginning of the Holocene, which aligns with the extinction of giant mammals. - **Option (b) Pliocene-Pleistocene**: The Pliocene precedes the Pleistocene, and while some extinctions may have occurred, the major extinction event for giant mammals is more closely associated with the Pleistocene. - **Option (c) Eocene-Oligocene**: This period is much earlier than the extinction of giant mammals and is therefore incorrect. - **Option (d) Pliocene-Miocene**: Similar to option (b), this period does not correspond with the extinction of giant mammals. ### Step 5: Conclusion Based on the analysis, the correct answer is **(a) Pleistocene-Holocene**. This is the period during which the giant mammals became extinct. ### Final Answer **(a) Pleistocene-Holocene** ---
