Answer

To determine in which blood group antibodies are absent, we can analyze the presence of antibodies in each blood group. Here’s a step-by-step solution:

### Step 1: List the Blood Groups
We start by identifying the four main blood groups:
- Blood Group A
- Blood Group B
- Blood Group AB
- Blood Group O

### Step 2: Identify Antibodies in Each Blood Group
Next, we will note the antibodies present in each blood group:
- **Blood Group A**: Contains **anti-B** antibodies.
- **Blood Group B**: Contains **anti-A** antibodies.
- **Blood Group AB**: Contains **no antibodies** (anti-A and anti-B are absent).
- **Blood Group O**: Contains **anti-A and anti-B** antibodies.

### Step 3: Analyze the Presence of Antibodies
Now, we analyze the information:
- Blood Group A has anti-B antibodies.
- Blood Group B has anti-A antibodies.
- Blood Group AB has no antibodies.
- Blood Group O has both anti-A and anti-B antibodies.

### Step 4: Conclusion
From the analysis, we can conclude that the blood group in which antibodies are absent is **Blood Group AB**.

### Final Answer
**Blood Group AB** is the blood group where antibodies are absent.
