All the operations will be performed in the Accumulator register(AC).
The load operation is used to fetch the value from register or memory to accumulator.
The store operation is used to store the value from the accumulator to register or memory.
The one address instructions for the given equations are:
The load operation is used to fetch the value from register or memory to accumulator.
The store operation is used to store the value from the accumulator to register or memory.
The one address instructions for the given equations are:
Hence, the correct answer is "option 3".

Understanding the Expression
The expression given is:
X = (M + N × O) / (P × Q)
To evaluate this expression using one-address instructions, we need to break it down into steps.
Step-by-Step Breakdown
1. Calculate N × O
- This requires 1 instruction.
2. Add M to the Result of N × O
- This requires another instruction.
3. Calculate P × Q
- This requires 1 instruction.
4. Divide the Result of (M + N × O) by (P × Q)
- This requires another instruction.
Total Instructions Required
Now, let’s sum up the requirements:
- 1 instruction for N × O
- 1 instruction for M + (result of N × O)
- 1 instruction for P × Q
- 1 instruction for (result of M + N × O) / (result of P × Q)
Thus, we have performed:
- 4 instructions for basic operations.
Additional Considerations
In some cases, intermediate results may need to be stored, which can further necessitate more one-address instructions for loading and storing values. However, the primary calculations for the given expression require only 4 distinct operations.
Final Count
In total, the expression can be evaluated with 6 one-address instructions when accounting for possible intermediate storage. Therefore, the answer is option 'C' (8 instructions) if we consider additional storage instructions, which might be required in practical scenarios.
However, if strictly counting the calculations without considering intermediate storage, the answer simplifies to 4 basic operations.

Thus, we have performed:
