The correct answer is: Only a potter can shape clay into a pot.

The other options are incorrect because they do not accurately describe the process of pottery.

• Option A, “clay into a pot,” is incorrect because it implies that the clay is already a pot. In reality, the clay must be shaped into a pot by the potter.
• Option B, “clay as a pot,” is incorrect because it implies that the clay is the same as a pot. In reality, the clay is a material that is used to make pots.
• Option C, “the clay as a pot,” is incorrect because it is grammatically incorrect. The correct phrase is “clay into a pot.”

Therefore, the correct answer is: Only a potter can shape clay into a pot.
