A man said to a lady, ''your mother's husband's sister is my aunt''. How is that lady related to that man?

Options

A. Daughter
B. Grand-daughter
C. Mother
D. Sister

Explanation

To solve the problem, we need to analyze the statement made by the man and break it down step by step.

### Step 1: Understand the statement
The man said, "Your mother's husband's sister is my aunt."
- Here, "your mother's husband" refers to the lady's father.
- Therefore, "your mother's husband's sister" means the sister of the lady's father.

### Step 2: Identify the relationship
- The sister of the lady's father is the lady's aunt.
- The man states that this aunt is "my aunt."

### Step 3: Determine the connection
- If the lady's aunt (the sister of her father) is also the man's aunt, it implies that the lady's father and the man's parent (either mother or father) are siblings.

### Step 4: Conclusion
- Since the lady's father and the man's parent are siblings, this means that the lady and the man are cousins.
- However, since the question asks how the lady is related to the man, and the man refers to the lady's aunt as "my aunt," it indicates that they share a closer relationship.

### Final Relationship
- The lady is actually the sister of the man.

Thus, the lady is the man's sister.
