Choose the correct option to complete the sentence.
The hospital staff ensured proper_________ conditions in every ward.

Correct option is D

The correct option to fill in the blank is (d) sanitary.
Explanation (with Hindi): Sanitary is an adjective meaning relating to hygiene and cleanliness (स्वच्छता/स्वास्थ्यकर संबंधी). The noun conditions needs an adjective before it; the standard collocation is sanitary conditions (hygienic conditions).
Example: After the inspection, the NGO certified that the slum clinic maintained sanitary conditions.
Why other options are incorrect:
· sanity: soundness of mind (मानसिक संतुलन/सद्बुद्धि)—a noun, not suitable before “conditions.”
· sanitarium: a medical rest-home (आरोग्याश्रम)—a noun, not an adjective.
· sanitery: incorrect/nonstandard spelling; intended word is sanitary.
