Answer:
C. the market demand curve understates the relative importance of the product and resources are therefore underallocated to its production.
Explanation:
Positive external benefits refer to third party positive side effects, above & beyond private marginal benefit to the concerned consumer. 
Eg : Education - Its consumption not only affects the concerned person, but the positive trickle down to the people & society around. 
Personal consumption decisions are based on : equalisation - of private marginal benefit (demand) curve & private marginal cost curve. However, goods having positive external benefits have real marginal benefit curve increased over private benefit curve, by the extent of extra marginal social benefit. 
So, market demand (based on private marginal benefit) curve understates the importance of product, and resources are therefore underallocated to its production (due to undervaluation of demand).

Answer:
 d. $119.32
Explanation:
The computation of the total of leiff online purchase is shown below:
= Video game price - discount + sales tax + shipping fee
where, 
Video game price is $128
The discount = Video game price × discount percentage
= $128 ×15%
= $19.2
The sales tax =  (Video game price - discount) × sales tax rate 
= ($128 - $19.2) ×5.3%
= $5.77
And, the shipping fee is $4.75
Now put these values to the above formula  
So, the value would equal to
= $128 - $19.2 + $5.77 + $4.75
= $119.32
