Final answer:
The Treaty of Anantpur as mentioned does not correspond with any widely recognized historic treaty. However, the Treaty of Greenville was an actual agreement between the United States and Native American tribes on the northwest frontier.
Step-by-step explanation:
The Treaty of Anantpur does not appear to be a widely recognized treaty throughout history; in fact, it may be a misnomer or a fictitious treaty not covered in historical records. Therefore, none of the options presented in the initial question (India and Pakistan, Afghanistan and Iran, China and Japan, Nepal and Bhutan) are correct with regard to the "Treaty of Anantpur."
Instead, we can provide information on a factual treaty that shares a similarity in naming convention: The Treaty of Greenville. The Treaty of Greenville was an agreement between the United States and Indians on the northwest frontier. This and other historical treaties, such as the Treaty of Tordesillas, reflect significant geopolitical negotiations.
