Ans.- (D)
Option A is wrong because coefficient of price of related good is positive so they are substitutes.
Option B and C are wrong because price of good, price of related good and income all affect the demand for your product.
Option D is correct because R^2= 0.98 which means that 98% of the variation is explained by these 3 variables.
