Select the correctly spelt word out of the four alternatives.
Answer & explanation
Answer: C) Hazardous
Rule: build the word from its root — hazard + the adjective suffix -ous = hazardous *(ख़तरनाक, जोखिम भरा)*.
The root keeps its single z and its -ard; the suffix is -ous, never *-us* or *-ious*.
Break it up: ha-zard-ous.
Why the others are wrong.
#B Hazardus — drops the o of the suffix *-ous*; English adjectives end in -ous (*famous, dangerous*), not -us.
#B Hazzardous — doubles the z; the root *hazard* has only one.
#B Hazardious — adds a stray i; -ious comes only when the root ends that way (*glory → glorious*), and *hazard* does not.
Answer: Hazardous
*Hazard + ous — nothing added, nothing doubled.*
Examples
- “Working in the mine is a hazardous job.”
