As per standards prescribed under the Factories Act 1948 for sanitation in factories, latrine accommodation should be provided at the minimum ratio of:

• A One latrine per 10 workers
• B One latrine per 100 workers
• C One latrine per 50 workers
• D One latrine per 25 workers ✓

Explanation

The prescribed standard is one latrine seat for every 25 workers, with separate enclosed latrines for male and female workers and access screened from view. The ratio of one tap for every 15 workers applies to drinking water points, a different provision often confused with sanitation. Numbers-based ratios such as these form a recurring cluster in PSM examinations and reward precise memorization.
