In the given questions, two quantities are given, one as Quantity I and another as Quantity II. You have to determine relationship between two quantities and choose the appropriate option.
`mn ne 0`
Quantity I. m=n Quantity II. `m/n`

Options

A. If Quantity I`ge` Quantity II
B. If Quantity I`gt`Quantity II
C. If Quantity I`lt`Quantity II
D. If Quantity I`=`Quantity II or the relationship cannot be established from the information that is given

Answer

To solve the problem, we need to analyze the two quantities given:

**Quantity I:** \( m = n \)

**Quantity II:** \( \frac{m}{n} \)

### Step 1: Analyze Quantity I
From Quantity I, we have:
\[ m = n \]

### Step 2: Substitute in Quantity II
Now we substitute \( m \) in Quantity II:
\[ \frac{m}{n} = \frac{n}{n} = 1 \]
This implies that:
\[ \text{Quantity II} = 1 \]

### Step 3: Compare the Two Quantities
Now we compare both quantities:
- Quantity I: \( m = n \) (which can be any non-zero value)
- Quantity II: \( \frac{m}{n} = 1 \)

### Step 4: Consider the Condition \( mn \neq 0 \)
Since \( mn \neq 0 \), both \( m \) and \( n \) cannot be zero. This means both quantities can take on any non-zero values, and since \( m \) is equal to \( n \), it follows that \( \frac{m}{n} \) will always equal 1.

### Conclusion
Thus, we can conclude that:
- Quantity I is equal to Quantity II.

Therefore, the relationship between the two quantities is:
\[ \text{Quantity I} = \text{Quantity II} \]

### Final Answer
The answer is that both quantities are equal.
