Choose the odd one out.

Options

A. Mother
B. Father
C. Sister
D. Sister-in-law

Answer

To solve the problem of choosing the odd one out from the given options, we can follow these steps:

### Step 1: Identify the Options
We have four options:
1. Mother
2. Father
3. Sister
4. Sister-in-law

### Step 2: Analyze the Relationships
- **Mother**: A direct blood relation.
- **Father**: A direct blood relation.
- **Sister**: A direct blood relation.
- **Sister-in-law**: Not a direct blood relation; she is related by marriage.

### Step 3: Group the Options
We can group the first three options (Mother, Father, Sister) as they all represent direct blood relations. The fourth option (Sister-in-law) does not belong to this group.

### Step 4: Identify the Odd One Out
Since Mother, Father, and Sister all share a direct blood relationship, while Sister-in-law is related through marriage, we can conclude that:
- **Odd One Out**: Sister-in-law

### Final Answer
The odd one out is **Sister-in-law**.
