I would say C because it makes the most sense.. good luck!
As mentioned in the question, wavy hair is a result of phenomenon of incomplete dominance where no allele is dominant over the other.
So if we say a man with curly hair (hh) marries a woman with straight hair (HH), we need to find out will their kids have straight hair or not.
Let us cross them:
Parents: hh X HH
Gametes: h : h and H :H
Offspring: hh: Hh: hH: HH
Probability of children with straight hair (HH) = 25 %
Probability of children with curly hair (hh) = 25%
Probability of children with wavy hair = 50 %
So there is a chance of 25 % that their kids can have straight hair.
Hope it helps!
4.3 Agricultural land. At present some 11 percent (1.5 billion ha) of the globe's land surface (13.4 billion ha) is used in crop production (arable land and land under permanent crops). This area represents slightly over a third (36 percent) of the land estimated to be to some degree suitable for crop production.
