**Core Concept**
Skimmed milk is a type of low-fat dairy product that has been processed to remove most of its fat content. The primary goal of skimmed milk production is to eliminate the milk fat globules, which are the main contributors to the calorie and fat content of milk.
**Why the Correct Answer is Right**
The correct answer is related to the lactation process and the composition of milk. Skimmed milk is devoid of milk fat globules, which are produced in the mammary gland during lactation. These globules are composed of a phospholipid membrane surrounding a core of triglycerides, which is the main source of fat in milk. By removing these globules, skimmed milk retains most of its nutritional value while significantly reducing its calorie and fat content.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not applicable as skimmed milk still contains lactose, a disaccharide sugar that is an essential component of milk.
* **Option B:** Skimmed milk may contain some residual casein and whey proteins, which are essential for its nutritional value.
* **Option C:** This option is incorrect as skimmed milk still contains water, which is the primary component of milk.

Skimmed milk is a good source of calcium, vitamins B2 and B12, and protein, making it a popular choice for individuals with high cholesterol or those who are lactose intolerant. However, it is essential to note that skimmed milk may have a different taste and texture compared to whole milk.
**Correct Answer: B. Skimmed milk is devoid of milk fat globules.**
