**Question:**

Which of the following does NOT belong to PRAM 3-phase instructions?

A. Write  
B. Local Computation  
C. Read  
D. Fetch  

**Explanation:**

This question tests your understanding of the PRAM (Parallel Random Access Machine) model, specifically its three-phase instruction process. The typical phases are:

1. **Read** Phase: Processors read data from the shared memory.
2. **Local Computation** Phase: Processors perform computations using data from the read phase.
3. **Write** Phase: Processors write results back to shared memory.

Identify which of the provided options is not part of these three defined phases.
