The correct option is C A crop that withstands salinity.
Wider adaptability is a term that is used to describe the crop's ability to tolerate changes like agricultural changes or the changes in the environment. If a crop has wider adaptability then such crops are considered to be strong enough to be prone to changes without getting damaged. However, if the wider adaptability is lacking then the crop will be affected by changed and as result will be damaged. For example, a crop that withstands salinity or climatic condition.
