Answer:
A) 3% decrease in the quantity demanded of pineapple.
Explanation:
We know that the demand curve is negative, which means that as price of a product increases, its demand will decrease.
In unitary elasticity(1) the change in demand means that the change in quantity demanded will be the same. A 0.75 elasticity will thus mean that the quantity demanded will change by a factor of 0.75 as compared to the change in price.  
Therefore when the price of pineapple increases by 4%, the quantity demanded will decrease by 4 * 0.75 = 3%
