Papaya seeds are added to adulterate which of the following?

Correct option is C

• Papaya seeds resemble black peppercorns in size, shape, and color, making them a common adulterant.
• They are cheaper, lighter, and lack pungency, allowing unscrupulous sellers to increase volume fraudulently.
• They cannot be used to adulterate mustard, tea, or cardamom because their appearance differs significantly.
