1. 1
2. 2
3. 3
4. 4

Answer 1

Correct Answer - Option 3 : 3

The correct answer is option 3.

3 memory operations: for Double word starting at Odd address.

2 memory operations: for Double word starting at Even address.

1 memory operations: for Single word starting at Odd address.

2 memory operations: for a single word beginning at an odd address

∴ Hence the correct answer is 3.
