Answer: Option (A) is correct.
Explanation:
Given that,
Variable costs = $17
Fixed costs to produce = $3
Product sells = $25
Homer Industries offers = 5,000 units
Unit selling price = $19
Shipping costs = $1.50 per unit
Net profit = Unit selling price - Variable costs - Shipping costs
        = $19  - $17 - $1.50
        = $0.50
Total increase in profit = 5000 units × Net profit
                   = 5,000 × 0.50
                   = $2,500
