Final answer:
The baker should refrigerate the cookie dough immediately before rolling it into balls. Therefore, the correct answer is D. Refigerate the cookie dough.
Step-by-step explanation:
The baker should refrigerate the cookie dough immediately before rolling it into balls. Refrigerating the cookie dough helps it firm up and prevents it from spreading too much during baking.
This ensures that the cookies maintain their desired shape and texture. Once the dough has been refrigerated, the next step is to roll it into 1-inch balls.
This step precedes rolling the dough into balls to ensure that once you have shaped the dough, you can immediately place the balls onto the prepared cookie sheet without them sticking. Preparing your work surface in advance facilitates a seamless baking process.
Therefore, the correct answer is D. Refigerate the cookie dough.
