Statement 1 is Correct: The Rigveda contains references to the use of an ashma chakra (stone pulley wheel) and ahava (strapped wooden pails) to draw water from wells. This supports the idea that irrigation from wells allowed agriculture to expand away from flood plains into areas like Punjab and Haryana, where groundwater was accessible.

Statement 2 is Correct: The use of draught-animal power, specifically oxen, to draw water from wells is supported by historical evidence. Oxen were domesticated and used for ploughing and pulling carts even before the Rigvedic period, as evidenced by archaeological finds from the Indus Valley Civilization. This supports the statement that draught-animal power was employed to draw water from wells.

Statement 3 is Incorrect: While the Rigveda mentions agricultural implements like parashu (axe) and datra (sickle), these references do not directly support the statements about irrigation and draught-animal power. They are more related to the tools used for clearing land and harvesting crops.

Therefore, the correct option is C, as statements 1 and 3 support the given statements about the Rigvedic period.
