Final answer:
The three layers of an espresso shot are heart, body, and crema.
Step-by-step explanation:
The correct answer is B) Heart, Body, Crema. When making an espresso shot, there are three distinct layers that form. The heart is the bottom layer, which is the darkest and most concentrated part of the shot. The body is the middle layer, which is less concentrated than the heart and contributes to the overall flavor. Lastly, the crema is the top layer, which is a golden-brown foam that forms on top of the espresso shot and adds a smooth texture and rich flavor.
