Explanation

To solve the question "Which of the following taxonomic categories includes all the others?" we need to understand the hierarchy of taxonomic categories. Here’s a step-by-step breakdown:

### Step 1: Understand Taxonomic Hierarchy
Taxonomic categories are organized in a hierarchical structure. The main categories from broadest to most specific are:
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species

### Step 2: Analyze the Options
The options given are:
- Family
- Order
- Genus
- Species

### Step 3: Determine the Relationships
We need to identify which category can encompass the others:
- **Family**: This includes multiple genera (plural of genus).
- **Genus**: This includes multiple species.
- **Species**: This is the most specific category and cannot include any of the others.
- **Order**: This includes multiple families.

### Step 4: Identify the Correct Answer
Since the order is the only category that can include family, genus, and species, it is the correct answer.

Thus, the answer to the question is:
**Order** (Option B)
