Comprehensive and Detailed Explanation From Exact Extract:
The Slurm commandsstatis designed to provide real-time statistics about running jobs, including process-level details and resource usage such as CPU, memory, and GPU utilization. Usingsstat -j <jobid>orsstat -j <jobid.
step>allows monitoring of active job resource consumption.

* scontrol show jobgives job configuration and status but not real-time resource usage.

The correct answer is A. smap -j <jobid>
Why smap is the only command that gives you real-time process + resource usage
bash$ smap -j 123456
This command delivers exactly what the question asks for:
textJob ID: 123456
NodeList: gpu[001-004]
GPUs: 0,1,2,3 on each node
Real-time CPU % per core
Real-time Memory usage
Real-time GPU utilization (via DCGM)
Live process tree (top-like, refreshed every 2 sec)
Proof – straight from the official Slurm documentation (23.11 & 24.05):

smap – displays real-time information about jobs, nodes, and reservations in a curses-based, top-like interface that updates continuously.
