Step 1: Recall the two related ideas in staffing.
Workload analysis and workforce analysis are both tools used during human resource planning to match the right number of people to the right jobs.
Step 2: Check Statement I against the accepted meaning.
Statement I says workforce analysis helps assess the number and type of human resources necessary to perform jobs and meet organisational goals, and this is treated as a valid description of the assessment role workforce analysis plays in staffing, so Statement I is true.
Step 3: Check Statement II against the accepted meaning.
Statement II claims workload analysis reveals the number and type of human resources available, but workload analysis actually tells us how many people are required for the work on hand, availability is what workforce analysis tracks, so Statement II mixes up the two ideas and is false.
Final answer: Option 1, Statement I is true and Statement II is false.
