Select the correctly spelt word out of the four alternatives.
Answer & explanation
Answer: B) Sustainability
Meaning: sustainability = the ability to keep something going over a long time without exhausting resources *(स्थिरता, संधारणीयता, निरंतरता)*.
Build the spelling.
sustain + able → sustainability
S-u-s-t-a-i-n-a-b-i-l-i-t-y — keep the full root sustain, then -ability (a-b-i-l-i-t-y).
Why the others are wrong.
#B Sustainibility — writes *-ibility*; the suffix comes from *-able*, so it is -ability.
#B Sustanability — drops the i of the root *sustain*.
#B Sustainablity — drops the i between *b* and *l*; *-able* becomes -abil-ity, not *-ablity*.
Answer: Sustainability
*-able words take -ability: capable → capability, sustainable → sustainability.*
Examples
- “Sustainability is key to environmental policy.”
