Verified step by step guidance

Understand the question: The problem is asking which protein source contains lactose. Lactose is a sugar found in milk and dairy products, so the protein source must be derived from milk.

Review the options: Analyze each protein source provided in the question to determine its origin and whether it is associated with milk or dairy products.

Option 1: Whey protein concentrate - Whey is a byproduct of cheese production and is derived from milk. Since milk contains lactose, whey protein concentrate may contain lactose unless specifically processed to remove it.

Option 2: Pea protein - Pea protein is derived from peas, a plant-based source. It does not contain lactose because it is not related to milk or dairy products.

Option 3: Soy protein isolate and Option 4: Egg white protein - Soy protein isolate is derived from soybeans, and egg white protein is derived from eggs. Neither of these sources is related to milk or dairy, so they do not contain lactose.
