Answer 1

The Correct Option is D

Step 1: Deadlock Conditions Explained.
Deadlock necessitates the simultaneous presence of all four essential conditions: 1. Mutual Exclusion: A resource is held exclusively, preventing sharing.
2. Hold and Wait: A process possesses at least one resource while requesting others.
3. No Preemption: Resources cannot be seized from a holding process.
4. Circular Wait: Processes form a cycle of waiting for resources held by others.

Step 2: Summary.
For deadlock to manifest, all four conditions must coexist concurrently.
