List II
1. no link step is required at all
2. easy to read and to debug
3. portable across machines
4. supports separate compilation

  • A.A-4, B-2, C-1, D-3
  • B.A-2, B-4, C-3, D-1
  • C.A-3, B-1, C-4, D-2
  • D.A-2, B-4, C-1, D-3

Answer: D

Each form suits a different setting. The choice affects how much work remains after compilation and how easy the compiler itself is to develop and to test. Many compilers emit assembly during development and machine code later.
