Correct answer: B — Respiratory surveillance with spirometry, symptom review and exposure-control escalation

Respirable crystalline silica can cause silicosis and COPD, and health surveillance is appropriate where residual risk remains. Surveillance commonly includes respiratory questionnaires and spirometry, supported by competent interpretation. Because measurements are near the WEL, control measures and RPE suitability need urgent review rather than relying on surveillance.
