(B) Working Set
(C) Deadlock
(D) Wait/signal
List - II
(I) Circular wait
(II) Condition variable
(III) Principle of locality
(IV) Mutual exclusion
Choose the correct answer from the options given below:

(A) [(A - IV); (B - III); (C - I); (D - II)]
(B) \( [(\mathrm{A}-\mathrm{IV}) ;(\mathrm{B}-\mathrm{III}) ;(\mathrm{C}-\mathrm{II}) ;(\mathrm{D}-\mathrm{I})] \)
(C) \( [(\mathrm{A}-\mathrm{III}) ;(\mathrm{B}-\mathrm{IV}) ;(\mathrm{C}-\mathrm{II}) ;(\mathrm{D}-\mathrm{I})] \)
(D) \( [(\mathrm{A}-\mathrm{III}) ;(\mathrm{B}-\mathrm{IV}) ;(\mathrm{C}-\mathrm{I}) ;(\mathrm{D}-\mathrm{II})] \)
✓ Correct Answer: Option A Verified Solution

📘 Step-by-Step Solution & Detailed Explanation:

  • (A) Critical region: needs mutual exclusion → (IV)
  • (B) Working set: based on the principle of locality → (III)
  • (C) Deadlock: circular wait is one of its necessary conditions → (I)
  • (D) Wait/signal: operations on a condition variable → (II)

So A-IV, B-III, C-I, D-II.

Answer: (A)
