Answer:
C). Landform A is a wetland and Landform B is a karst landform.
Step-by-step explanation:
As per the given descriptions, the third statement is most likely to be correct as it matches the characteristics of 'wetland and karst landform.' Wetland is described as the landform which is covered mostly with water, with occasional marshy and soggy areas. Thus, it contains marshes and swamps while Karst is a type of land formation, usually with many caves formed through the dissolving of limestone by underground drainage which leads to dissolution of bedrock. Therefore, option C is the correct answer.
